基坑支护圆环受力分析

Mechanical analysis for circular ring support of foundation pit under uniform pressure

在基坑支护设计中,基坑平面接近方型或圆形时,采用圆环支撑,圆环支撑的截面与圆环的直径大小有直接的关系,本文通过力学推导,找出了它们之间的关系。

Foundation pit plane is close to square and circle,circular ring support is used in support of foundation,section size of circular ring is related to circular ring radius;this paper derive relation of circular ring section size and radius.
