摘要
根据JTG D63-2007《公路桥涵地基与基础设计规范》,编制了按m法计算弹性桩的规范表格,并借助表格法和Midas civil模型2种计算方法进行计算。实例计算结果对比表明:对于单桩,Midas模型与规范法得到的结果差不多;对于承台多排桩,2种方法的偏差与影响深度内下层地基土的比例系数有关,工程应用时,建议以规范法对Midas模型进行修正。
Based on JTG D63-2007 Code for Design of Ground Base and Foundation of Highway Bridges and Culverts, this paper has compiled a specification table for calculating elastic piles according to the m method, and the calculation was carried out by means of table method and Midas civil model. The comparison of the calculation results of the example shows that for single pile, Midas model and standard method get similar results;for multi-row pile on cap, the deviation of the two methods is related to the proportional coefficient affecting the depth of the inner subsoil. In engineering application, it is suggested to modify the Midas model with the standard method.
