%0 Journal Article %T Discussion of Type Selection and Design on Waterproof Curtainfor Deep-Foundation Pit in Neighbouring Huangpu River Area %J - %D 2018 %X Based on the distribution characteristics of burial depth and thickness of confined aquifers adjacent to the Huangpu River area, for the deep-foundation pits of two floors basement, the conventional tri-axial deep stirring pile is usually used to cut off the confined aquifer; for the deep-foundation pits of three floors basement or beyond, the burial depth and thickness of confined aquifer in each site are quite different, correspondingly, the selection and design of the waterproof curtain of the confined aquifer is relatively complicated. In order to induce engineering accidents due to the failure of the water curtain, the problem of confined water had to be studied and dealt seriously and scientifically. Based on the two engineering examples adjacent to the Huangpu River, this paper focuses on the complexity of the confined water problem of the deep-foundation pit projects in three floors basement or beyond, and the selection and design of the waterproof curtain.Different design schemes are recommended by discussing the economy and rationality of design schemes, evaluating construction feasibility and analyzing the complexity of construction quality control. The result of research shows that for the waterproof curtain of the deep-foundation pit in three floors underground or more, considering the large construction depth, the TRD method and the underground diaphragm wall are better %K Deep-Foundation Pit %K Waterproof Curtain %K More Than Three Floors Underground %K Adjacent to Huangpu River Area %U http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=207&doi=10.11648/j.ijnrem.20180304.12
