摘　　要：水泥搅拌桩是一种软基处理形式,它以水泥为主要固化剂,通过搅拌桩机将水泥喷入土中,使水泥与土壤发生一系列的理化反应,硬化软土,提高地基强度(适用于处理淤泥、淤泥质土、素填土、软一可塑粘性土等土层)。本工程根据项目实际情况,采用单轴水泥搅拌桩加H型钢支护用于五星酒寤北侧、西侧垂直支护,该技术具有操作工艺简单、可操作性强、工期短、环境污染小等优点,具有良好的经济效益和社会效益。Cement mixing pile is a form of soft foundation treatment.lt uses cement as the main curing agent.The cement is sprayed into the soil through the mixing pile machine to cause a series of physical and chemical reactions between the cement and the soil to harden the soft soil and improve the strength of the foundation(suitable for the treatment of silt,silty soil,plain fill,soft-plastic clay and other soil layers).According to the actual situation of the project,this project adopts uniaxial water mixing piles and H-shaped steel support for the vertical support of the north and west sides of the five-star hotel.This technology has simple operation technology,operability,short construction period,and low environmental pollution advantages,with good economic and social benefits.
