Abstract: At present, for the soft soil ground such as newly reclaimed silt and mud flows, it is generally considered that the integral plastic drainage board with anti-clogging reinforced effect is more desirable than the ordinary plastic drainage board; while for the soft soil ground such as newly reclaimed clay and silty clay, the comparative field test results show that the integral plastic drainage board and the general plastic drainage board have similar reinforced effects, that is to say the advantages of the integral plastic drainage board is not obvious.
