10.4
Extracted text: 10.1 Refer to the braced cut shown in Figure P10.1. Given: y = 16 kN/m², d' = 38°, and c' = 0. The struts are located at 3.5 m center-to-center in the plan. Draw the earth-pressure envelope and determine the strut loads at levels A, B, and C. 4.5 m 1 m A Sand y = 16 kN/m d'= 38° 2.5 m c'= 0 В 3 m 1.5 m Figure P10.1
Extracted text: 10.4 Determine the sheet-pile section modulus for the braced cut described in Problem 10.3. Given: oa = 170 MN/m². 10.3 Refer to Fig. P.10.3. Redo Problem 10.1 with y = 18 kN/m², 4' = 40°, c' = 0, and the center-to-center strut spacing in the plan = 4 m. - 3.5 m- 1 m A Sand y = 18 kN/m³ d'= 38° c'= 0 2 m B 2 m 1.5 m Figure P10.3
