摘要
为了稳定井壁,提高工作效率,减少或避免事故的发生,需要确定地下连续墙合理的泥浆密度,归纳总结出了黏性土层、砂岩及卵砾石层,以及考虑土拱效应的干燥砂层、储水砂层的稳定槽壁的泥浆密度计算算法,并提供算例进行实际计算,证明泥浆密度的算法对现场具有重要的指导意义。
The mud density of diaphragm wall should be reasonable in order to keep the groove wall stability,improve work effiency,reduce or avoid accident.Authors summed mud density calculating method for viscous layer,sandstone and gravd cobble bed,as well as dry sand layer and water sand.Further,calculative examples are designed to prove the guide function of mud density design method.
