地基弹性抗力一般都是分布力,其分布规律往往不能用静力平衡条件求得.抗力不知,结构内力的计算也会发生困难,若能求得抗力.结构的内力就可以用力学方法进行分析.因此,本文将提出采用完全连续的弹性体模型计算桩、墙各单元在荷载作用下的位移,再用完全不连续的Winkler模型来表达其地基抗力。这样可克服二类极端模型的缺点,更精确地求得地基弹性抗力.
Elastic resistance of the foundation are generally distributed forces, the distribution of the law often can not be obtained using static equilibrium conditions. I do not know the resistance, the calculation of structural forces will also be difficult, if we can find resistance. The internal forces of the structure can be analyzed mechanically. Therefore, this paper will propose a completely continuous elastic model to calculate the displacement of the pile and wall under load, and then use the completely discontinuous Winkler model to express its foundation resistance. In this way, the shortcomings of the two extreme models can be overcome and the elastic foundation resistance can be obtained more accurately.
