摘要
给出了地下墙泥浆槽壁坍体底斜面涉及地下水面而未及地表面情形下的坍体极限平衡方程式和物理意义明确的转换式,导出了最危险状态的坍底面临界倾角和相应的极限平衡状态的护壁泥浆临界相对密度的迭代解公式及实用的近似求解方法,并给出了判别坍底临界倾斜面是否涉及地表的充分必要条件和简化的充分条件。
In this paper the limit equilibrium equation and its transformed form inwhich physical conception is clear for the slump mass of the vertical trench side of diaphragmwall in case that the bottom of slump mass crosses groundwater surface and does not groundsuffice is presented.And the fO,rmula of iteration methods calculating the critical dip angleof slump massl S bottom in the most dangerous state and the corresponding critical specificgravity of slurry in the limit equilibrium state are deduced. The ample prerequisite and thesimplified ample condition distinguishing whether the dip bottom of the slump mass crossesground surface or not are given.
