摘要：

In order to explore the processing method of foundation stabilization. Large-scale field tests on a soft ground composed of a 2-5 m thick mucky soil were conducted in Jiangsu province, involving five ground improvement methods, on a soft ground composed of a 2-5 m thick mucky soil. These tests included packed-drain with explosion, plastic-drain with surcharge, cement-jet-pilling at different spacing, and sand mat. During 14 months' in situ testing, the deformation behavior of the improved soft ground was investigated, and by comparing with the reinforcement scheme, the settlement after completion and economical efficiency of project are also studied. These results are expected to provide the reference value for the selecting of soft ground treatment methods and design parameters of high-speed rails.
