一、前言日本新潟,十胜冲和美国阿拉斯加强烈地震后,砂土液化造成的灾害引起了人们的重视和研究。由于饱和松散砂土在地震或其他动荷载作用下极易产生液化并导致地基失效,危及建筑物的正常使用和人的生命安全,因此必须设法研究如何经济、有效地防止砂土液化的产生。我们首次在国内某8度地震区,在房屋建筑的饱和松散粉细砂土地基处理中,采用了振冲法加固,取得良好的成果。实践证明,用振冲法施工并设置石料排
I. INTRODUCTION Following the strong earthquake in Japan’s Niigata, Tokachi, and Alaska, the disaster caused by the liquefaction of sand caused people’s attention and research. Because saturated loose sand is easily liquefied under earthquake or other dynamic load and causes ground failure, endangering the normal use of buildings and human life safety, it is necessary to study how to economically and effectively prevent the production of sand liquefaction. For the first time in our country’s 8 degree earthquake area, in the construction of saturated loose silty sand ground for house construction, vibroflotation method was used to reinforce and achieve good results. It has been proved that vibrating method is used to construct and set stone rows
