桥头深层处理中高压旋喷桩和塑料排水板应用

Comparison between high-pressure rotary jet grouting pile and plastic drainage plate in deep treatments of bridgehead

介绍了塑料排水板和高压旋喷桩处理桥头路基的加固原理、设计方案和沉降观测成果,重点分析了两种处理方案达到的沉降速率、工后沉降、固结度等,结论表明预压期和预压荷载对于桥头地基处理效果至关重要。

This paper introduces the strengthening principle, design scheme and settlement observation achievement of the treatment of bridgehead roadbed. Moreover, this paper emphatically analyzes the settlement rate, settlement after construction and degree of consolidation that these two schemes can achieve. The conclusion shows that the pre-compression term and pre-load is very important for the foundation treatments effects.
