Abstract

To study reinforcement effect and bearing characteristics of long-short cemen-t soil piles composite foundation in deep soft soils, the loading test in situ on the bearing characteristics of long-short cemen-t soil piles composite ground in deep soft soils is carried out. The stresses of long piles, short piles and soil have been measured; and pile-soil stress ratio of composite ground with cemen-t soil long-short piles and its variation with the load have been studied in deep soils. According to pile-soil stress ratio, it has been found that stress ratio increases firstly and then decreases and finally tends to stability. It has also been revealed that the sequence of primary piles and secondary pile have been changed before and after critical load.
