摘要

针对某湖滨路的拓宽改造工程

选取地基土层最不利的断面进行数值模拟

并采用强度折减法研究其整体稳定性。数值分析结果表明

加宽后的新路基稳定性较差

安全储备不能满足要求

需要采取加固措施。对初步设计提出的仅采用土工格栅和采用土工格栅+水泥搅拌桩这两种不同加固处理方案进行了数值分析。计算结果表明

相比仅采用土工格栅

采用土工格栅+水泥搅拌桩进行软基处理可以有效地减小不均匀沉降、提高路堤的整体稳定性。本文的实例研究可供类似工程参考和借鉴。

Abstract

For a road widening project along lakeside

a control section of its soil strata was numerically simulated to study the global stability of the widened embankment with the strength reduction method.The analysis indicates that the stability of the widened road embankment does not satisfy the safety requirement so that special engineering measures are needed to improve the soils.Two different measures were numerically simulated according to the preliminary design scheme.The first one is to use geo-grids

and the second to use cement mixed piles plus geo-grids.The numerical study indicates that the second measure can reduce the differential settlement and improve the stability against sliding more effectively than the first one.The work in this paper can provide reference and illustration to similar projects.
