摘要
对传统的抗滑桩内力计算“K”法作了一些改进,如建立了滑动面上下统一的坐标系,将桩视为一个整体进行考虑,通过合理的假定,保证了桩身在滑动面处内力和位移的连续性。同时,采用著名的MATLAB数学软件设计了“K”法的计算程序,适用于滑坡推力和桩前滑体抗力分布的各种形式以及抗滑桩为刚性桩和弹性桩的情况。实例计算结果表明,较之传统的查表法,该方法有效地提高了抗滑桩内力和位移计算速度和精度,同时可得到理想的可视化计算结果,有助于抗滑桩结构的优化设计。
Some improvements are made on the traditional 'K' method about intemal force analysis of the stabi1izing pile against 1ands1ide. For ex-amples, a universal coordinate including above and below sliding surfaces is established. The pile is considered as a whole body. The continuity of inter-nal forces and displacement is assured through reasonable supposition. Meanwhile, the well - known mathemaic software MATLAB is used to design aprogram of 'K' method. The program can be applied to all sorts of distributions of lateral force and soil reaction as well as rigid or elasic stabilizing piles.Compared with the traditional method, a calculated case shows that this method can effectively improve calculation speed and precision of internal forcesof stabilizing piles. Reasonab1e visual resu1ts of calcu1ation can be obtained. The visual figures are helpful to optimize the structural design of stabilizingpiles.
