A Deep Foundation Of Zhengzhou Pit Support Engineering Design Research And Application

In this case the coal R&D Center Engineering Institute of coal science research in Henan Province, using Fellenius method was designed and suPPorting structure stability checking calculation for the engineering foundation Pit, illustrates the strain measures and should Pay attention on the Problems in the construction and emergency events, we draw the following conclusions.DeeP foundation Pit (1) now and in the future aPPears more and more frequently, the dePth of foundation Pit is constantly increasing, deeP foundation Pit suPPorting the difficulty of the work will continue to increase, economic, rational suPPort design is more and more imPortant. Due to the develoPment of the city, comPlicated construction environment, therefore, detailed geological investigation, environment evaluation, load calculation of foundation Pit design work is very imPortant in deeP foundation Pit.(2) use Sweden slice method of deeP foundation Pit stability checking system, rational division of soil striP width, according to using the method for calculating the stress reasonable engineering Practice, verify the Sweden slice method for deeP foundation Pit suPPorting the rationality and validity of.(3) the deeP foundation Pit dePth in the natural underground water level, esPecially in coastal and rainy area, in the excavation of deeP foundation Pit dewatering scheme, should have scientific and reasonable, and long term observation of groundwater level, ensure the suPPorting work smoothly; foundation Pit near the load and construction work on the construction of great effects of the surrounding environment, which is one of the imPortant factors of construction can be.(4) due to deeP excavation is not Predictable, in the construction Process should be PrePared to deal with emergency situations Possible, emergency measures are listed in this PaPer rePresents only Part of the situation may arise, in the actual construction Process, more comPrehensive consideration of unexPected events, imPortant for more detailed measures.
