Abstract

Clays and silts have the low strength compressive. Clay is a kind of fine grain soil that has a low bearing capacity and very sensitive to changes in water content. To improve soil conditions then soil reinforcement is done by using lime substance. The clay soil sample is a type of high plasticity clay that taken from Rawa Sragi- Jabung- East Lampung district and then the silt soil sample is taken from Yosumulyo-East Metro- Metro City. Based on previous experiments, that soil is included in soft clay and high plasticity category. Based on Unified Soil Clasification (USCS), clay belong to CL category, While silts belong to Cl-ML category. In unconfined compressive strength test, clays and silts with variation of curing time and unsoaked condition, soil with hydrated lime mixtured with modified proctor compacted, for clays,Qu value increased with the addition of lime content.  It get Qu optimum value increased when it has 12% hydrated lime content, 28 days of curing time. For silts Qu optimum value inscreased when it has 12% hydrated lime content and 28 days of curing time. Hydrated lime adding could inscred unconfined compressive strength but with longer curing time duration (28 days). Because the greater Qu soil value is the greater soil bearing capacity.Keywords: Hydrated Lime, Clay, Silt, Unconfined Compressive Strength, Soil Bearing Capacity

Abstract

Landslide is a natural disaster that often occurs in Lampung Province, particularly in WestLampung regency. The sliding occurs due to an increase in soil pore water stress in the rainyseason. Based on the research on the slopes, there is a safety factor value that can be used as areference for the degree of slope stability. One method to analyze the value of slope safety factoris by using the Geostudio Slope / W 2007 program.In this study, some cross sections of slope were simulated with 4 different water table conditions.The required soil properties index are: cohesion, c; natural angle of repose, φ; and unit weight ofdensity, γ .The analysis result shows that slope transversal cut shape have influence on slope stability. Theanalysis results on slopes with saturated conditions have a safety factor value of <1.25 and areclassified on unsafe slopes. In the unsaturated condition the whole simulation is classified as astable slope with a safety factor value> 1.25. Based on the analysis result, it can be inferred thatthe slope has insecured status. Thus, it is suggested to conduct such actions in order to preventlandslide.Key words : soil, slope stability, safety factor, geostudio slope/w.

Abstract

The strength of infrastructure buildings is influenced by the type of soil underneath. One type of land that is widely found in the land in the province of Lampung is fine-grained soil. The fine grained soil is meant soft clay and organic clay. Construction of the above clay will experience significant land subsidence constraints when given the loading. The load that causes the pore water pressure increases so that the pore water out and soil decreases consolidatively. Therefore, it is necessary to study soil degradation using box test and bamboo concrete mats as a means of land degradation. The result of clay decline testing using boks modeling and bamboo concrete mat, soft clay experience faster rate of process of decline (Cv) than organic clay. The magnitude of soft clay (Cc) decline is less than that of organic clay. Soft clay volumes are also changing volume (Mv) faster than organic clay. Coeficient of compression(av) of soft clay is also faster than organic clay. The total decline in total soil over a 20 year period on soft clay is smaller than that of organic clay. Keywords : Clay, Test Box, Bamboo Concrete Mattress, Soil Consolidation

Abstract

ABSTRACTThe soil layer is the bottom layer that has function to forward the load from construction on it. But not always the basic soil layer is able has function properly as the bearing capacity. The soil stabilization method with lime additive is an alternative that can be used in planning on a unstable soil construction. The aim of this research is to know the physical characters of clay soil in Sidodadi Asri area, Jati Agung subdistrict, South Lampung regency and the type of silt soil in Yosomulyo area, East Metro District, Metro City. And also to know the increase of the bearing capacity of both types of soil with variation of curing time of 7, 14 and 28 days. From the result of the physical character research and mechanical of original soil samples obtained so it can be concluded that land taken from Sidodadi Asri village classified as clay with high plasticity, while the soil from yosomulyo village is clay with low plasticity. And on the CBR test in the ideal soaking conditions with ideal lime content showed that the increase of CBR value in each soil type along with the increase of the curing duration of 2.8%, 4%, 6.4% and 10.2% in clay and 2, 2%, 3%, 3.6% and 6% in silt soils. This suggests that the ideal lime composite in addition to the curing duration gives a positive effect to increase bearing capacity soil or CBR value. Keywords: Lime, Stabilization, Clay and Silt Soil, Soaked CBR.

Abstract

Tanah yang banyak mengandung lempung mengalami perubahan volume ketika kadar air berubah. Kembang susut tanah yang besar, berakibat pada struktur bangunan di atasnya, karena tanah lempung organik umumnya memiliki kuat geser yang rendah. Sampel tanah diambil dari Daerah Jabung, untuk dilakukan pengujian permodelan laboratorium pada kotak kaca dengan alat vane shear dan direct shear dengan berat tanah ±117.000 gr. Pada pengujian geser langsung kondisi tanah  tak jenuh di kedalaman 30 cm didapatkan nilai kuat geser sebesar 0,1286 kg/cm2, pada pengujian geser baling didapatkan 0,61 kg/cm2 dengan daya dukung tanah sebesar 1,4103 kg/cm2, kedalaman 50 cm didapatkan nilai kuat geser sebesar 0,1196 kg/cm2, pada pengujian geser baling didapatkan 0,61 dengan daya dukung tanah sebesar 1.7018 kg/cm2. Pada kondisi tanah jenuh kedalaman 30 cm didapatkan nilai kuat geser pada pengujian geser langsung sebesar 0,1286 kg/cm2, pada pengujian geser baling sebesar 0,61 kg/cm2 dengan daya dukung tanah sebesar 1,0347 kg/cm2, kedalaman 50 cm didapatkan nilai kuat geser sebesar 0,0861 kg/cm2, pada pengujian geser baling didapatkan 0,46 kg/cm2 dengan daya dukung tanah sebesar 1,3997 kg/cm2. Dari hasil pengujian uji geser langsung dan uji geser baling diketahui bahwa nilai kuat geser pada uji geser langsung lebih kecil dibandingkan dengan uji geser baling.

Abstract

Pemadatan tanah merupakan salah satu pekerjaan penting dalam setiap proyek konstruksi, tanggul, waduk dan konstruksi sipil lainnya, tanah yang belum padat atau masih kondisi gembur harus dipadatkan untuk meningkatkan untuk meningkatkan kekuatan tanah, sehingga dengan demikian meningkatkan daya dukung pondasi di atasnya, serta juga berfungsi untuk mengurangi besarnya penurunan tanah yang tidak diinginkan. Untuk itu, dalam penelitian ini akan dilakukan pemadatan tanah dengan menggunakan metode standard proctor di laboratorium dan menggunakan pemodelan alat uji tekan pemadat modifikasi untuk mengetahui pengaruh jumlah lapisan terhadap derajat kepadatan tanah. Tanah yang digunakan berasal dari Tirtayasa, Bandar Lampung. Pengujian proctor menggunakan beberapa lapisan yaitu lapisan 2, 3, 4, dan 5. Sedangkan alat tekan pemadat modifikasi menggunakan tekanan 5 MPa, 10 MPa, 15 MPa. Lapisan yang digunakan yaitu lapisan 2, 4, dan 6 pada setiap tekanan. Hasil penelitian menunjukkan bahwa berat volume maksimum (γdmaks) sebesar 1,49 gr/cm3 pada pengujian metode standard proctor dengan hasil pada alat tekan pemadat modifikasi didapat nilai (γdmaks) sebesar 1,66 gr/cm3.
