Method for calculating anti-upheaval stability of narrow foundation pit
A method for calculating the upheaval resistance stability of a narrow foundation pit comprises the following steps that 1, the insertion depth D of a supporting structure, the width B of the foundation pit and the distance x from a lowest support to the bottom of the foundation pit are set, and when # imgabs0 #, the circle center is located at the intersection point of the lowest support and the supporting structure at the moment, namely R = D + x; 2, along with the increase of the insertion depth D of the retaining wall, when # imgabs1 #, the foundation pit is in a critical state of a wide foundation pit and a common foundation pit, and the circle center is still located at the intersection point of the lowermost support and the supporting structure; 3, the insertion depth D is increased, and when # imgabs2 is adopted, the circle center of the sliding face gradually moves downwards along with the increase of the insertion depth till the bottom of the foundation pit and the sliding face pass through the bottom of the supporting structure and the radius # imgabs3; 4, the insertion depth D continues to be increased, and when # imgabs4 is adopted, the radius of the supporting structure with the circle center located below the bottom of the foundation pit and the radius of the sliding face are half of the width of the foundation pit; according to the retaining wall, the length of the retaining wall is greatly optimized, and huge economic benefits are brought to a narrow foundation pit.
一种窄基坑抗隆起稳定性的计算方法，包括以下步骤：步骤1：设支护结构的插入深度D，基坑宽度B，最下道支撑到基坑底部的距离x，当#imgabs0#时，此时圆心位于最下道支撑与支护结构的交点处，即R＝D+x；步骤2：随着增加挡土墙的插入深度D，当#imgabs1#时，此时该基坑处于宽基坑与一般基坑的临界状态，圆心仍位于最下道支撑与支护结构的交点处；步骤3：增大插入深度D，当#imgabs2#时，滑动面的圆心随着插入深度的增大而逐渐向下移动，直到基坑底部，滑动面通过支护结构的底部，半径#imgabs3#步骤4：继续增大插入深度D，当#imgabs4#时，圆心位于基坑底部以下的支护结构，滑动面半径为基坑宽度的一半，即#imgabs5#本发明大大优化挡土墙的长度，这将为窄基坑带来巨大的经济效益。
