摘要
对《建筑基坑支护技术规程》JGJ 1 2 0 99所推荐的潜水非完整井涌水量计算公式进行研究后 ,发现《规程》所推荐的公式是一极值函数 ,意味着该公式的应用只有在界定的条件下才能使用 ,进而通过相关量分析 ,提出了界限含水层概念 ,继而通过拟合得出了界限含水层的计算方法 。
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.
