High ground water level will bring a series of geotechnical engineering hazards,especially for areas with large dewate-ring requirements,large groundwater changes and poor geology,and it will bring greater challenges to the underground con-struction.Combined with the engineering examples of the high groundwater level and the silty soil,at first,the advantages and disadvantages of different dewatering methods were compared,scientific and effective dewatering treatment technologies were selected,and then the construction process and precautions were evaluated,the dewater effect was analyzed,and finally the lat-er settlement monitoring was followed up,so as to accumulate more technical application experience for the same type of con-struction projects in the future.The results show that,according to the actual site conditions,the dewater of the light well point is very effective in this project,and it can meet the subsequent construction.The post settlement was monitored,and the construction monitoring satisfied the requirements of the specification.
