On Inspection of Bearing Capacity of Mixing Pile Composite Foundation by Load Test

Mixing pile composite foundation,as a kind of treatment for soft foundation,is applied extensively in engineering construction;however,due topile group effect,the result of load test for single pile composite foundation with small load plate is larger than the actual result leading to relative insecurity.The bearing capacity of single pile composite foundation has high correlation with that of composite foundation,as a result,it is proposed that where load test for single pile composite foundation is used to inspect composite foundation,a reduction factor is needed to guarantee the engineering safety.
