Analysis of Fast Drained and Consolidated Mechanism of Soft Soil under Excessive Pore Water Pressure

Abstract

Fast drained and consolidated mechanism of soft soil under excessive pore water pressure generate excessive pore water pressure in the soft soil through the addition of vertical and horizontal drainage channel as well as the applied load, because the drainage path is significantly reduced, the seepage velocity speed up and water excreted rapidly under the excessive pore water pressure, also, the effective stress increase rapidly between the soil particles and accelerate consolidation of soft soil so as to improve the strength of soft soil.
