不均匀地基堆筑工程稳定性分析

Stability Analysis of Load Engineering in the Presence of Uneven Foundation

某堆筑工程原有地基包含松散填土、中风化泥岩等,由于地基的不均匀性,势必会引起堆筑体的不均匀沉降,必须对地基进行处理。初步设想为对土质地基进行改良,但是改良的范围难以确定。因此采用数值模拟的方法对堆筑体进行稳定性计算,发现对部分土质地基进行改良即可,无需改良整个土质地基。对部分土质地基加固后堆筑体的稳定性得到了很大的提高,满足了工程要求,分析结果为类似工程提供参考。

The uneven foundation of a piling engineering project,which is composed of loose fill and mid-weathered mudstone,needs treatment due to uneven settlement of the project. The initial consideration is to improve the soil foundation,but the range of improvement is difficult to determine. In view of this,stability calculation is carried out for the built body by using numerical simulation method. Results reveal that only parts of the soil foundation needed to be reinforced without changing the whole soil foundation. The stability of the built body was greatly improved by reinforcing parts of the soil foundation. The analysis results in this paper provide meaningful reference for similar projects.
