摘　　要：对kranz法的原理进行了分析,推导出计算公式,并结合结合工程实例,提出了锚固体整体稳定性验算的Kranz法中假设支点b点的选取位置,认为b点选择为桩的反弯点(即桩入土端中左侧被动土压力与右侧主动土压力相等的点)比较合适。Kranz, a common methods of stability analysis for pile-anchor supporting system,is discussed combined with a practical engineering example;This paper put forward the selection of assumed fulcrum ＇b＇ by Kranz method of Overall stability calculation of anchorage body;The point ＇b＇ option for the inflection point of pile is more appropriate.The inflection point is that the passive earth,thant is pressure on the left side equal to the active earth pressure on the right side.

关 键 词：桩锚支护 稳定性分析 kranz法 假设支点(支点选取方法)
