从传统振冲碎石桩与“气协”振冲碎石桩两方面,简略介绍了复杂地层中大功率振冲碎石桩的施工方法,并分析了各种施工方法的经济性,结果表明:“气协”振冲碎石桩施工法不仅能提高工程质量,还能减少能源的消耗,具有良好的经济效益。
The construction methods of high-power vibro-impact gravel piles in complex strata are briefly introduced from the traditional vibro-replacement stone columns and the air-assisted stone columns, and the economic benefits of various construction methods are analyzed. The results show that the construction method of “AAC” vibro replacement stone column can not only improve the quality of the project, but also reduce the consumption of energy and has good economic benefits.
