In terms of Biot consolidation theory and by using integral transforms methods, the fundamental solutions of circular load or point sink in the interior of the half space are established.

Emendation of drawdown in pumping wells for numerical modeling of groundwater flow;

In the three-dimensional value simulations for pumping and dewatering,the processing for pumping well is a difficulty.

Based on construction of groundwater heat exchangers for ground source heat pump system in Chengdu Jinsha Ruin Museum,key technologies were introduced such as selection of reasonable tube well structure,proper arrangement of pumping well and injection well,closing of equipments at wellhead and secondary well washing.

Closing technique of sluice way and pump well in Xuanwuhu Lake tunnel;
