| Abstract: | The phenomenon of the sand running and water pouring in the excavation of the cushion cap of the Zhihe River's Extra Large Bridge has severe influence on the smooth construction. In order to guarantee the construction quality, the construction scheme of the excavation supported by the dewatering by well group is adopted and the test of the dewatering by well group is made. This paper introduces the selection of the field parameters of the dewatering by well group and the calculation of the design parameters of the well group, which can be used for reference for the similar engineering. |
