问题 问答题 简答题

路基边坡稳定分析有哪几种方法,各适应什么场合?稳定系数K的含义?

答案

参考答案:

力学分析法和工程地质法。一力学分析法直线法适用砂类土,土的抗力以内摩擦为主,粘聚力甚小。边坡破坏时,破裂面近似平面。圆弧法适用于粘性土,土的抗力以粘聚力为主,摩擦力甚小。边坡破坏时,破裂面近似圆弧形。二工程地质法根据不同土类及其所处的状态,经过长期的实践和大量的资料调查,拟定边坡稳定值参考数据,在设计时,将影响边坡稳定的因素作比拟,采用类似条件下的稳定边坡值。直线法中K=F/T圆弧法中K=Mr/Ms。

The confused teacher was expecting a(n)       correct answer, three. She was disappointed. “Maybe the child did not listen      ” she thought. She     “Laiq, listen carefully. If I give you one apple and one apple and one apple, how many apples will you have?”

The teacher now had a      smile. Her approach had succeeded. She wanted to      herself. But one last thing remained.      she asked him, “Now if I give you one apple and one apple and one more apple how many will you have?”
Confidently Laiq answered, “Four!” The teacher was     , “How Laiq, how?” she demanded in a little impatient voice.
In a voice that was      and hesitating young Laiq replied, “Because I already have one     in my bag.”
The story tells us:      someone gives you an answer that is      from what you expect, don’t think they are wrong. There shall be an angle that you may not have thought about yet.
