Geotechnical Analyses Of Guizhou Hotel, Shilong Mei, Baoshan Huang

International Conference on Case Histories in Geotechnical Engineering

This paper presents the geotechnical analyses of Guizhou Hotel, a thirty story (102-m high) building situated under complicated karst engineering geological conditions. Comprehensive geotechnical investigations prior to the design included the bore hole sampling, insitu ultra-sound velocity testing, groundwater well-pumping, and laboratory testing for rock strength. Based on the field and laboratory data, the bedrocks within the construction site (about 20,000 m2) was divided into four engineering geological units Ia, Ib, Ic, and Id, ranging from simple engineering geological condition (Ia) to very complicated geological condition (Id). Different subgrade bearing capacities were selected for the four units based on field …
