CFG桩复合地基处理在高速公路加宽中的应用

在高速公路加宽改造项目设计和施工中,差异沉降量的控制已成为影响工程施工进度、质量以及道路运营行车效果和安全的关键因素。结合工程实践,分析CFG桩的设计及受力分析,CFG桩作为一种刚性桩,具有承载力高、工后沉降量小、稳定性好、工期快的特点,值得推广。

The CFG Pile Compound Ground Treatment in the Highway Widens Application

In the highway widens in the innovation project design and the construction, the unequal settle- ment quantity＇s control into affects the project construction progress and the quality as well as the road us- age driving effect and the safe key aspect. Analyzes the CFG pile the design and the stress analysis, the CFG pile takes one kind of rigid pile, has the supporting capacity to be high, after the labor, subsides the quantity to be small, the stability is good, the time quick characteristic, is worth promoting.
