护坡板桩内力计算方法的探讨

等值梁法、弹性线法和弹性支点法，是工程中目前最常用的支护结构内力计算方法，并被用来对护坡桩进行内力分析．三种方法的计算结果有时彼此差别很大，而计算结果的正确性正是实际工程经济和安全的关键．在对三种方法理论分析的基础上，对计算结果进行了分析比较，弹性线法和等值梁法无法考虑桩的刚度、支撑点位移及被动土的抗力参数对计算结果的影响，仅适合一定刚度范围内的护坡桩的内力计算。

Discussions of calculating methods of forces in the bearing piles

The equivalent beam method, the elastic-line method and the elastic-reaction method are often applied presently in the calculation and analysis of the forces of bearing piles in practical engineering. The three calculating results are often far different from each other. Moreover, the accuracy of calculating results is important in some economical and safe respects of practical engineering. The three calculating results based on their theory are compared with each other in the paper. It concludes that stiffness of piles, displacements of the bearer and parameters of the elastic-reaction have nothing to do with the calculating results in the equivalent beam method. And this method is just applied for calculating forces in some areas of stiffness of bearing piles.
