Question 1 A smooth wall retains two layers of soil as shown in Figure 1. The groundwater table is located at 3 m below the ground surface. Suatu dinding licin menahan dua lapisan tanah seperti dinurjuikan pada Rajah 1.Aras air bumi berada pada 3 m dari permukaan tanah Construct a diagram of earth pressure against the wall. Jika terdapat keadaan akrif, bina rajah bagi tekanan bumi terhadap dinding tersebut 7 i) (2 Marks/Markah) ii) Estimate the total active...
Question 2 (a) A 4 m high masonry retaining wall of width 1.8 is built to retain a 2-layered soil profile shown in Figure 2 on Bonham Road on Hong Kong Island with a surface sucharge of 20 kPa. The soil parameters are given in the figure. During raining season, ground water rises to interface between Soil 1 and Soil 2. Assume that there is no friction between the vertical wall and the soils. The sliding friction angle between the...
A retaining wall is to be constructed in a normally consolidated clayey sand deposit in the figure below. Ground water table is lmbelow the bottom of the excavation. A 20 kN/m2 surcharge pressure is applied over a wide area at the ground surface. Assume the wall moves into the excavation. Consider long-tem analysis (as it is usually the more critical analysis in excavation problems). Ignore capillarity as shown 20 kPa Clayey sand T17 kNm Y-20 kNm 5 m c'-10 kPa...
