侧向变形

• Research results show that foundation pit slope soil structure destroy characteristic is subgrade shear strain destroy , namely , it is gradually destroy . lateral displacement of retaining and protecting piles has relations with embed depth , load grade and strength index parameter . soil displacement and timbering pile displacement are in harmony with deformation
  研究结果表明，基坑边坡土体具有地基整体剪切变形破坏的特点，系渐进破坏的过程；支护桩侧向变形是桩嵌固深度、荷载大小、土体强度参数变量的函数；土体的位移和支护桩的位移满足变形协调条件。
