On-site Experimental Study on Disposal of Muck Foundation by Dynamic-static Drainage Consolidation Method
摘要
Abstract
Combining with the project of muck foundation disposal at Nansha Port, Guangzhou and using the indexes, such as excess pore water pressure, layered settlement and shearing strength, the depth and the effect of the reinforcement on muck foundation by means of dynamic-static drainage consolidation are studied through on-site experiment. The result shows that the increment of total tamping energy can increase the effective reinforced depth obviously. When tamping energy is given, tamping four or five times with the tamping energy in single point every time to be controlled less than 900 kN. m has superior reinforced effect and depth than tamping three times ; the reinforced depth and effect by means of heavy hammer and low drop distance tamping are superior to those by light hammer and high drop distance.关键词
