摘要：The silt has the properties, such as low strength and slow drainage; so it is usually treated by precompression method. For short construction period and low cost , a new drained consolidation method-drainage consolidation due to excessive pore water pressure for silt is tested: fist, the sand is replaced in the surface of silt for horizontal drain; and then, the plastic drain boards is applied for vertical drain; finally, the excess pore water pressure is generated by surcharge loads and dynamic consolidation and the drainage consolidation is fast under the excess pore water pressure. The result of the settlement observation and acceptance test shows that the result of drainage consolidation due to excessive pore water pressure for silt soft soil is remarkable. © (2011) Trans Tech Publications.
