Review of research progress on key disposal techniques of pile foundation in karst area

Abstract

It is necessary to study the key disposal technology of pile foundation in karst area during the development of pile foundation. In this paper, the development status of the key disposal technology of pile foundation was compared and analyzed from two aspects: the research progress of the comparison and selection of pile foundation design and construction scheme, the problems encountered in the construction of pile foundation in karst area and the research progress of treatment methods. The shortcomings and problems in the research of key disposal technology of pile foundation in karst area were studied, and the following conclusions were drawn: It is the priority among priorities to formulate scientific and quantitative reference basis for pile foundation construction scheme and convert engineering geology into data information. It is an important way to solve the problem of pile foundation construction in karst cave area to develop new piles and increase their adaptability to geological conditions. In the construction of pile foundation in karst area, the probability of accidents should be reduced as much as possible and the possible accidents should be stopped at the prevention stage. The research results provide technical support and scientific guidance for the calculation of bearing capacity of pile foundation and the key disposal technology in karst area.
