水利插板桩内力计算方法探讨

Discussion on Calculation Method of Internal Force of Hydraulic Sheet Pile

针对目前缺乏水利插板桩护岸内力计算方法的问题,探讨和分析了插板桩计算原理,推导了插板桩挡土板和锚固桩的内力及位移计算公式,并以江苏省南通市某河道护岸为例进行了验算。结果表明:所推导的公式力学意义明确,公式相对简单,便于设计人员计算,可为类似工程设计提供参考。

In response to the current lack of internal force calculation for water conservancy sheet pile revetment,the calculation principle and method of sheet pile are discussed and analyzed.The calculation formulas for the internal force and displacement of sheet pile retaining plate and anchor pile are derived.And a river revetment in Nantong City of Jiangsu as Province is checked.The result shows that the derived formulas have the clear mechanical significance,are relatively simple,and are easy for designers to calculate,which can provide reference for the design of similar projects.
