| Abstract: | After studying on the calculation formula for water emerging capacity of non-complete well of dive recommended in JGJ 120-99 "Technical Rules of Support and Protection of Construction Foundation Pit", it is found that the formula recommended in "Rules" is an extreme value function. It means that the application of the formula could be adopted only in the boundary condition. So it puts forward the conception of limited water-bearing stratum through the analysis of correlation capacity, then obtains the calculation method of limited water-bearing stratum through the proposal. At the same time, it puts forward the method for well point hydraulic calculation in thick li mited water-bearing stratum and in the combination of Zamalin Formula as well as the determination method for application condition. |
