| 摘 要： | 软土高填方路基施工过程中,土内自由水难以及时排出,产生超静水压力。在后续施工过程中,随着路基高度的增加路基不再被压密,导致固结过程所需的时间延长,工期滞后。本文根据软土高填方路基的施工特点和软土路基的应力增长特点,计算分析了其下软弱土层中孔隙水压力和有效应力的变化规律,采用应力路径法研究了软土路基的优化处理方案,可供同类工程参考。 |
| 关 键 词： | 软土高填方路基 超静水压力 有效应力 路基处理 应力路径 优化设计 |

Optimization design on soft foundation post-processing procedure for highway thick filling area |
|
| Abstract: | In the course of construction, the free pore water in the weak soil of highway foundation is seldom discharged immediately, and the excess pore water pressure comes into being. Consequently, the thick filling does not consolidate in the following process of construction, which results in the delay of completing. Based on the features of filling construction and stress increment in the foundation, the characteristic of pore water pressure and its diversification are determined. The optimization design process is put forward in light of stress path method, which may be used as a reference in similar project. |
| Keywords: | thick filling on highway soft-foundation excess pore water pressure effective stress highway foundation processing stress path optimization design |
