| Abstract: | In this paper, according to lots of information and data about engineering, the calculation of foundation pit supposition radius is discussed, when precipitaion area is bigger and a quarter of circle. The embedment depth of Well-point-tube in different soil layers within the depth of precipitation is analyzed. How to definite permeability coefficient and estimate precipitation time in different soil layers within the depth of precipitation is presented. At last, some suggestion on construction is given to offer basis for estimate and control of investment. |
