[热点探讨]边坡位移警戒值 [复制链接]

主要是加强对建筑物侧及管线附近基坑的变形、测斜，
以及降水监测吧

不知开挖基坑采用地下连续墙还是什么方法开挖基坑？

通过时间-速度曲线来进行边坡的滑坡预测是说服力的，基坑中通常提出警戒值。边坡好像没有说明

For the earth-retaining structure, some regulations recommended that the maximum lateral deflection should not exceed 0.5%H. some researchers mentioned the measured value is about 0.2-0.3%H.
in addition, generally the lateral deflection of the wall is related to the surrounding settlement around the wall. so when calculation was employed, the two deformation should be considered together.

这个问题不错！
千分之三的基坑深度作为位移警戒值，这是比较一般的经验吧

有道理，另外和土质有关

对于边坡位移极限值的规定，能否给一些文章出处，比如0.3%-0.5%H的出处，我急需用这个，谢谢

楼上讨论的0.3%这个经验值有没有出处，规范、文献都行，能否指明出处？

超过千分之三（在砂土中）和千分之三至千分之五（粘性土中）时
