ANALYSIS OF REDUCED COEFFICIENT beta|IN FORMULA FOR BEARING CAPACITY OF CEMENT-SOIL MIXED PILE COMPOSITE FOUNDATION

The reduced coefficient in formula for designing for bearing capacity of cement-soil mixedpile composite foundation was determined by the experiences and the range of is wide. So, it is difficult to accurately calculate bearing capacity of composite foundation. Based on the interaction of pile and soil, this paper discusses various factors influencing the reduced coefficient . By comparing the field static load test results of some typical engineering projects, the reduced parameter is analyzedand suggested its reasonable value.
