目前,国内外处理软弱地基的方法很多,而且通过实际工程中的不断应用,都不同程度地得到发展和完善。其中,振冲碎石桩加固技术是一种应用比较广泛的地基加固技术,该理论提出已40多年,我国开始应用也已将近20年。结合各地应用该项技术的成功经验,笔者拟对汤原县待建的两处防洪涵闸的地基采用同一技术处理,现做简要论述。 一、工程概况 该两处水闸均位于汤旺河低漫滩区。根据地质钻探资料查明,该两处水闸闸基地质情况大致相同,均为新生代松散沉积物,表层为2m左右的粘土层,以下为10m左
At present, there are many ways to deal with soft foundations both at home and abroad, and through continuous application in practical projects, they have been developed and improved in varying degrees. Among them, the vibration-assisted stone column reinforcement technology is a more widely applied foundation reinforcement technology, the theory has been proposed for more than 40 years, our country has begun to apply for nearly 20 years. Combined with the successful application of the technology around the successful experience, I intend to Tangyuan County to be built two flood control sluices foundation using the same technology to deal with, do a brief discussion. First, the project profile The two sluices are located in the Tang Wang River floodplain area. According to the geological drilling data, the geological conditions of the sluice gates in the two sluices are roughly the same, all of which are Cenozoic loose sediments with a clay layer of about 2 m on the surface and the following 10 m
