地基土的非线性力学模式探讨

AN INVESTIGATION ON THE NON-LINEAR MECHANICS MODEL OF THE SUBSOIL

本文在寻求异形基础沉降计算的应力解答过程中,根据模型基础的实测资资料探讨了应力课题的非线性模式,并将直接应用到北京国际饭店实际工程的沉降计算中,其计算值与实测值比较符合.在土的本构关系模型未付诸应用以前,这是解决实际工程非线性应力分布问题的实用途径.它能提高沉降计算精度.特别适合异形基础计算。

When exploring the stress solution of settlement calculation for the special shaped foundation, based on the measured data of the model foundation this pa- per researches the non-linear model type of the stress problem, and it is direc- tly used in the settlement calculation in the Beijing International Hotel pxoj- ect and the calculated values are found to have closer agreement with measur- ed values. As the constitutive relation of the soil is not known and has not been put into practice, this is a practical method to solve the non-linear stress distributioi. problem of the actual project. It can be increased the accuracy of the settlement calculation, and the special shaped foundation is especially app- licable.
