- Abstract
Based on the distribution law of karst caves in engineering projects, the influences of karst cave parameters (number, maximum diameter and top depth) on the stress and top settlement of pile foundation, bedrock and karst cave are analyzed. The results show that the size and location of the cave have little influence on the internal stress and settlement of pile foundation. When two caverns exist at the same time or the volume of caverns is large, the internal stress and settlement of pile foundation increase slightly. When the diameter of karst cave is large, the stress of soil near pile foundation is also large. It can provide the basis for pile foundation design in karst cave prone areas, and also provide technical support and guidance for the safe operation of practical projects.
