Experimental Study of Quality of Prefabricated Drain Cores

The quality of the core of prefabricated drains is one of the key issues in improving soft soils by drained consolida-tion and in practice,it can be judged if it meets the engineering requirements only by visual inspection.This paper describes that the laboratory results of buckling tests and longitudinal flow capacity tests indicate that cores with poor outer appearance may affect the result of drained consolidation of soil,which is hoped to help promoting the production and standardization of utilization of prefabricated drains inf uture.
