嵌岩变截面桩的应用与计算

The Application and Calculation of Non Uniform Pile Embedded into Rock

简要论述嵌岩变截面桩的应用条件及优点。分别采用各层地基竖向、横向反力系数为常数，建立轴向、横向位移函数通解及导数的矩阵式。引入桩顶、桩端边界条件，桩的连续条件，求解积分常数。该方法全部可采用电算完成，并经论证及验算，对于具有超固结粘土和硬壳层的土质情况，该方法比其它方法更接近于实际。

The application condetions and advantages of the non un iform pile embedded into rock has been discussed.The general solution and deriva tive matrix formulations of axial and transverse displacement function has been established by regarding fhe axial and transverse reaction coeflicients od strat ification foundation as constants respectively.The boundary conditions of pile b utt and pile tip and the continuous condetions of pile are quoted to find the so lution to the integration constant.This can be done by the electric computation independently,and it is proved to be more practical than other methods in the ca se of overconsolidated clay and crust.
