旋喷搅拌桩在软土地基处理工程中的应用

摘要

介绍了铁路工程中常用的软基处理方法，通过将目前软土地基加固方法中常规的水泥土搅拌技术和高压射频注浆技术进行有机结合，提出了旋喷搅拌桩的加固特点，对加固效果进行了初步试验和分析，并在工程实践中取得了成功，取得了明显的经济和社会效益。对探索在软黏土地基处理的新加固方法，做了有益的尝试，为类似工程地质条件下的地基处理实践，提供了可以借鉴的成功案例。%Main treatment method of general soft foundation in railway construction was introduced in the paper, treatment effect of jet⁃grouted mixing pile was proposed by combining the technology of cement deep mixed with jet technology effectively. Prelim⁃inary test and analysis for treatment result of jet⁃grouted mixing pile was raised. It was of great economic value and social benefit to popularize the new treatment method for the soft soil of high moisture content and organic matter foundation, successful case provided in the paper may be served as a reference for foundation treatment in similar engineering geological conditions.
