RESEARCH ON EFFECTIVE REINFORCEMENT DEPTH OF DYNAMIC COMPACTION TO THE SUBGRADE OF A STATION

摘要

A floodplain near the sea for container station and yard ground was treated by dynamic compaction method with 6 000kN-m dynamic energy. Calculate the effective reinforcement depth of the construction with Menard Method, Blliam Calculation Method, Liu Haichong Calculation Method, Zhang Yongjun Method, specification lookup table and other 8 methods, and have it compared with the results from load test at site and dynamic penetration test. It shows that: for artificial base filled with crushed stone soil, Zhang Yongjun Formula and specification lookup table are more appropriate.
