| Abstract: | Research purposes: It is very difficult to conduct construction of the pile foundation in karst area because hole collapse,leakage of thick liquid,drill jam,drill burying and concrete leakage often happen during construction.These seriously affect the quality and security of the construction of pile foundation.Thus,it is very necessary to do the study on the measures to be taken for ensuring the smooth construction.Research conclusions:Through the repeatedly studies and tests in constructions of the pile fo... |
