强夯置换法加固填海路基的试验研究

在深圳地区强夯置换法加固填海路基应用非常广泛，并在实践中取得了较好的处理效果。但由于强夯置换法尚未形成一套成熟的设计计算方法，因此，施工前往往在现场选取典型试验区进行试验性施工来确定工艺技术参数，以指导大面积工程施工。本文结合深圳市高新技术产业园南区市政道路软基处理工程实例，通过两个试验区的强夯试验研究，确定了用于指导近20万m^2路基处理的施工技术参数。

Experimental Study on the Subgrade of Reclamation Strengthened by Dynamic Replacement Method

In Shenzhen area the subgrade of reclamation strengthened by dynamic replacement method has found widespread application, and has obtained a good processing effect in practice. However, a set of mature design calculations method for the dynamic replacement has not formed. So the typical pilot area need be selected to determine the technology parameters for the total project construction. This article introduces the project example concerning the soft subgrade improvement of South Shenzhen High-Tech Industrial Park, in which through experimental studies of two pilot areas, the construction technology parameters were determined for 200,000 m2 area of the soft subgrade improvement
