城市复杂路基换填处理法应用分析

Replacement Method'S Application in complex roadbed Disposal

在城市建设过程中,经常会遇到复杂的杂填土及性质极差的软土地基,一般的施工方法是对杂填土和软土进行特殊处理,如浅层换填法。本文就其基本原理、适用范围、设计计算进行总结,并结合工程实例对浅层换填法的应用进行深入研究。

During the construction of city, there are many mixed backfill and soft ground. Tamping replacement in shallow layer is the most ordinary disposal measure for the complex ground. The aspects like action principle, scope of application, design and calculation are summarized. At the same time the replacement method in shallow layer is conducted an in--depth research combining an engineering instance.
