Abstract

Swelling and shrinkage abilities of soils are dangerous for buildings. According to Hardiyatmo (2014) There are two types of swelling in expansive soils that are the movement of lateral (horizontal) and axial (vertical). Oftentimes the deformation of soils cannot be supported by building stiffness. This damage can be seen in retaining walls, tunnel walls, and etc. With the aims to identify an expansive soil and to know its lateral and axial strains, an experimental study was performed. Swelling tests were conducted in a specimen having diameter (d) of 4,5 cm and height  (h0) of  2 cm with the variations in : 1) water content wopt = 31% and 18%; 2) vertical pressure (pv) 1 kPa, 3.5 kPa and 6.9 kPa; and 3) membrane thickness (t) 0.7 mm and 0.5 mm. The strain in the axial direction was measured with a dial gauge that was set vertically parallel whereas the lateral strain is by measuring changes in diameter of the specimen with a digital caliper measurement tools. Based on the analysis on the identification results, the observed soil is classified as expansive soil with the expansion potential is high average. The test results show the same potential for the occurrence of lateral and lateral strain if the lateral retention (e.g. retaining wall) is weak. The largest lateral and axial soil development occurred at water content w0 = 18% are 15.7% and 15.8% respectively.

Abstract

The landslide of the upper slope in the excavation work of the spillway SadawarnaDam Package II Subang occurred after rain, precisely at the STA location from0+500 to 0+520. The purpose of the study was to compare soil reinforcement on theprevious spillway slope using geomat and shotcrete with soil reinforcement usingsoil nailing. Based on soil data the spillway slope consists of two types of slopes, theupper slope consists of CL (BS:03) while the lower consists of ML (BS:04). Theshear strength parameters C and Phi of both slope soils are quite high. Using PlaxisV.21, Slope/W and Seep/W, with C and Phi the slopes were found to be stable.However, in reality there was a landslide on the upper slope. Therefore, backanalysis was performed by lowering the strength parameters of the top soil adjacentto the slope until the landslide was realized. The reinforcement used on the twoslopes was different, the upper slope used geomat while the lower slope usedshotcrete, then the geomat was changed to soil nailing. Two seasonal models wereapplied to all reinforcements. The results showed that the factor of safety valuesfrom the back analysis modeling in the wet season using geomat and shotcrete wereless than 1 (Unstable). However, reinforcement using soil nailing has a SafetyFactor higher than 1.5. Based on these results, soil nailing can be a solution tominimize landslides on the spillway slope.

Abstract

Piled raft system proves to be more effective on such problematic soft soil conditions. It takes the high vertical load and used to bring the settlement, differential settlement and tilting of structure within the permissible limit. Piled raft system proves to be cost effective than the conventional pile foundation system. Piled raft foundation accounts for complex soil-structure interaction, which needs interaction between structural engineer and geotechnical engineer. Geo-foam application is introduced below the footing to enhance floating resistance. The performance behavior of piled raft foundation in clayey soil and layered soil is carried out using laboratory experimental and then verified by 2D PLAXIS. There is a significant relationship between the decreases in settlement of the piled raft due to hydrostatic uplift.
