振冲碎石桩加固沼泽化湿地铁路路基机理研究

Mechanism research of the railway foundation reinforcement of the vibro-replacement stone column in the swamping wetland

针对高原沼泽化湿地路基的特殊土质,结合碎石桩在地基加固中的作用特点,提出了用振冲碎石桩加固的方案,对碎石桩复合地基的受力性状进行了多方面研究,根据有限元计算结果分析了桩身荷载传递规律。

According to the special soil of the swamping wetland subgrade in the plateau, the author puts forward the reinforcement scheme of the vibro-replacement stone column combined with the action characteristics of the gravel pile in the foundation reinforcement, studies the force character of the gravel pile composite foundation from various aspects, analyzes the law of the load transfer of the pile based on the finite element calculation results.
