成层土单桩有限里兹单元法分析

本文将成层土单桩问题划分成有限个单元，每个单元设定一个含待定参数的位移函数，用位移交分法求得待定参数，得到近似解．本文对照现场试验，与考虑分层的积分方程法作了比较，证明本文法是可行的

Analysis on single piles in layered soils in finite Ritz elements method

To solve the problem on single piles in layered soils,this parper devides the computingarea into finite elements and for each element an approximate displacement funtion which includes undecided parameters is chosen, using displacement calculus of variations to solve theundecided parameters and obtains approximate solution. Comparing with the field test, acomparation with the solution which treats the layered soils with intergral eqtlation method ismade, which proves the method of this paper is rational.
