摘要
以软土路基特征为立足点,根据其在地基承载力、含水量等方面的具体特点,探讨相应软土路基施工工艺,主要包含冻结法、土工织物铺垫、使用添加剂、砂垫层处理、软土路基表面处理、高压喷射注浆法、粒料桩处理等。通过分析认为,对于软土路基的处理有多种方法,相关工程人员需根据实际情况进行合理选择与应用,切实提高软土路基承载力与抗剪强度。希望通过对软土路基施工工艺的探讨为工程人员提供参考,以便在软土路基施工中选定最具可行性的施工工艺。
Taking character of soft soil subgrade as foothold, according to its specific characteristics of foundation bearing capacity, water content, etc., to explore corresponding soft soil subgrade construction technology, mainly including freezing method, geotextiles bedding,use additives, sand cushion processing, soft soil subgrade surface treatment, high pressure jet grouting method, aggregate pile treatment, etc.Through the analysis, it is concluded that there are many methods available for the treatment of soft soil subgrade, and relevant engineers should choose and apply them reasonably and effectively according to the actual situation, so as to effectively improve the bearing capacity and shear strength of soft soil subgrade. It is hoped to provide reference for engineers to select the most feasible construction technology in the construction of soft soil subgrade.
