摘要
以单支点桩锚支护结构为例,应用等值梁法和自由端法对土层参数分别采用分算与合算两种方法进行计算,结果表明:当各土层参数差异较大时,采用分算与合算计算得出的插入深度、支点力、最大弯矩等参数均相差较大,且对支护结构的设计精度有较大的影响;从计算的结果可以看出,选用自由端分层法计算得到的结果较为合理。
Taking single fulcrum pile-anchor retaining structure for example, use equivalent beam method and free-end method to determine soil parameters by layering calculation and average calculation. The result indicates that when there are wider differences among soil layers, the depth of penetration, reaction of supports and maximum bending moment calculated by equivalent beam method are much different from that by free-end method, which has great influence to design. The result calculated by free-end-layering method is more reasonable.
