| 中文摘要: |
| 在建筑物均质地基地震液化总应力判别法的基础上，针对非均质建筑物地基，利用锥体传力机制，求得地基中的附加动应力场，对于复杂成层地基，提出了可以直接求解地基中孔隙水压力的地震液化有效应力法判别方法。结合多孔介质动力学理论，给出了横向不均匀的复杂地基的分析方法。 |
| 英文摘要: |
| Based on the total stress method, the cone model theory is introduced to calculate the dynamic stress field of subsoil, so that the pore water pressure under the building can be evaluated directly. The effective stress method is suggested to evaluate the liquefaction potential of inhomogeneous building's subsoil. With the help of the theory for multi phased medium, a method is given to analyze the complex layered and inhomogeneous soil foundation. |
