摘要
依据换填法的原理及其作用效果,首次将该方法应用于基坑支护工程中.结合青岛某工程实例,借助理正岩土软件分析了原有基坑土和拟换填土的开挖边坡稳定性,并得出了不同坡度和不同坡面宽度情况下的边坡稳定系数,最终给出了换填边坡的设计型式.通过工后的支护效果监测,该换填边坡是稳定的.
According to the principle and effect of changing-filling method,this method is well applied to foundation supporting project for the first time.Combining a project example in Qingdao,the slope stability of the original foundation-soil and filling-soil are analyzed with the help of the Lizheng geotechnical software,and slope stability factors are got under the different gradient and different slope width conditions,and finally the changing-filling slope＇s design form is made.Through the supporting effect monitoring,this changing-filling slope proves to be stable.
