Quiz
1、多选题:
Which of the following statements are correct?
选项:
A: Most retaining walls have different degrees of deformation and displacement
B: If the retaining wall is directly cast on the rock foundation, the calculation based on the static earth pressure is generally more in line with the actual stress situation.
C: When checking the stability of the retaining wall, the value of passive earth pressure cannot be used all the time, generally 30%.
D: For passive earth pressure, it generally occurs when the displacement of the wall to the filling direction is relatively large, and the displacement is required to reach 2% -5% of the wall height. Therefore, it is economically reasonable to use passive earth pressure to design the retaining wall
答案: 【 Most retaining walls have different degrees of deformation and displacement ;
If the retaining wall is directly cast on the rock foundation, the calculation based on the static earth pressure is generally more in line with the actual stress situation.;
When checking the stability of the retaining wall, the value of passive earth pressure cannot be used all the time, generally 30%.】点我阅读全文
