摘要
本文从泥浆的性能和土层的特点出发,对混凝土帷幕凿井法泥浆护壁机理进行了研究。首先从泥浆渗透作用与泥皮的形成过程研究了泥浆的性能对槽壁稳定性的作用,然后研究了泥浆对整个槽壁稳定性的作用以及泥浆对单个土颗粒的作用进行了研究。
In view of the property of slurry and the peculiarity of true soil, the mechanism of slurry dado with concrete curtain wall method in shaft excavation has been studied in this paper. First, from the straining action of slurry and the formation rocedure of mud membrane, the influence of the property of slurry on the stability of the sides of the trench has been, studied, then, the function of slurry to the stability of whole slurry trench has been studied; finally, the function of slurry to single grain in soil has been studied.
