Abstract

The soft clay soil has expansive behavior that expands when exposed to water, this will be very dangerous to the construction to be built on it, because clay soil generally has a low shear strength and high compressibility. To know the parameters and characteristics of strong clay soil shear in an area, can use vane shear test and direct shear test. The soil samples were taken from Jabung, East Lampung for testing laboratory modeling on glass box with vane shear and direct shear tools with a weight of  ± 130,730 grOn the direct shear tests when soil conditions remolded at a depth of 30 cm shear strength values obtained at 0.0743 kg/cm2, on vane shear test obtained 0.38 kg/cm2 with soil bearing capacity of 0.6048 kg/cm2, at a depth of 50 cm obtained a shear strength value of 0.0779 kg/cm2, on vane shear test obtained 0.54 kg/cm2 with soil bearing capacity of 0.6738 kg/cm2. In saturated soil conditions a depth of 30 cm obtained a shear strength value in the direct shear test of 0.0553 kg/cm2, the vane shear test of 0.46 kg/cm2 with a bearing capacity of 0.4116 kg/cm2, a depth of 50 cm obtained shear strength value of 0.0743 kg/cm2, the vane shear testing with a 0.65 kg/cm2 earned bearing capacity of 0.6308 kg/cm2.

Abstract

Soil landslide is one of the most common in the field of Geotechnical due to increased shear stress of a soil mass or decrease in shear strength of the soil mass. In other words, the shear strength of the soil mass is not able to bear the burden of work going on. Disruption to the stability of the slope can be caused by various human activities and natural conditions. Unstable slopes is dangerous to the surrounding environment, therefore slope stability analysis is needed. In this case the condition of Padang Tambak – Liwa street KM.227+400 Lampung Barat experience landslide up the road. The purpose of this study is to evaluate the value of the safety factor and to plan the dimension and stability of sheet pile to the landslide on Padang Tambak – Liwa street KM.227+400 using the Plaxis v.8.2 of computer program. The result of this study obtained the value of safety factor at the initial condition of 0,7106, with displacement of 12,71 x 103 m.

Abstract

Pembangunan daerah menjadi prioritas pemerintah saat ini, seperti pembangunan Jalan Tol Lintas Sumatera. Pembangunan sangat erat kaitannya dengan pekerjaan tanah, karena tanah merupakan salah satu material yang memegang peranan penting dalam mendukung suatu konstruksi. Umumnya, suatu konstruksi dibangun dengan elevasi yang tidak sesuai, sehingga pekerjaan galian dan timbunan perlu dilakukan. Untuk mendapatkan tanah timbunan dengan kualitas yang baik, diperlukan pemadatan agar memperoleh tanah yang stabil dan memenuhi persyaratan teknis untuk membangun suatu struktur.. Pada penelitian ini membandingkan energi pemadatan tanah metode proctor modified dengan alat tekan pemadat modifikasi untuk tanah timbunan pilihan. Sampel tanah yang digunakan adalah tanah timbunan pilihan, berasal dari Desa Gedung Agung, Kecamatan Jati Agung, Lampung Selatan. Pengujian alat tekan pemadat modifikasi ini terdiri dari 4 tekanan berbeda yaitu 5 MPa, 10 MPa, 15 MPa dan 20 MPa, menggunakan tiga sampel tanah pada masing-masing tekanan. Hasil pengujian di laboratorium menunjukkan bahwa berat volume maksimum (γdmaks) sebesar 1,706 gr/cm3 pada pengujian metode proctor modified dengan hasil pada alat tekan pemadat modifikasi didapat nilai tekanan sebesar 10 MPa.
