| The development of the building and transportation aroused the development ofthe excavation. And the depth of the excavation is more and more big and become thedeep excavation. Because of the rapid development of computer technology and thespread of personal computers, it is possible that computer used for engineering designof the deep excavation.The groundwater destroy the footing groove by way of the lose of latent, theflow of sand, pipe gush, sudden gush and so on. The groundwater destroy the footinggroove by way of the lose of latent, the flow of sand, pipe gush, sudden gush and soon. The first in the article we study the storage of groundwater and the characteristicsof the move. The groundwater destroy the footing groove by way of the lose of latent,the flow of sand, pipe gush, sudden gush and so on. The groundwater destroy thefooting groove by way of the lose of latent, the flow of sand, pipe gush, sudden gushand so on. The we study the way of vacuum point well, multi-stage point well,electro-drainage point well ,ejector point well, self absorbing well, buried well pipingthe groundwater. Finally the thesis in a large quantity investing and study on theories,developed the Dewatering software according to the norm of the station and theprofession.In a word, the software provides a set of fast and intellective designs systemwhich can be used to decline the water of deep excavation of construction. It includesten windows, five modules and fifteen categories.Dewatering applicable to the basic engineering, geological engineering,geotechnical engineering, precipitation and underground construction design.According to the layer with water, the permeate coefficient and the request ofdeclining the depth of water , Dewatering can judge intellectively and combine withthe reasonable dewatering methods, finally output the report of writing, theconstruction arrange of declining water, the curve diagram of dewatering which cansatisfy the demands of construction and designing.
