Application of Comprehensive Technology for Soft Foundation Reinforcement
The rapid construction development in China southeastern coastal areas has increased the de-mand for reinforcement of soft soil foundations such as dredged soil,marine soil,and blown fill soil.Among them,geocells and high-pressure jet grouting piles are two relatively mature technologies used in other types of projects,and are suitable for the reinforcement of clay,silty clay,silty clay and other soil materials.This article introduces a case which used two comprehensive technologies,geocell replacement cushion technology and high-pressure jet grouting pile technology,to complete the reinforcement of the soft soil foundation.The design calculation theoretical value.The field practice results show the applicability and effectiveness of the process.The results show that the total settlement of the foundation with the three-layer geocell replacement cushion is 29 mm,and the total settlement of the foundation with the grid-reinforced mattress cushion and high-pressure jet grouting pile technology is 17 mm.These two comprehensive technologies are suitable for complex construction environment and quickly increase the bearing capacity of the shallow foundation in the short term and control the settlement within the required range of normal use.That provide a feasible solution for the process selection of subsequent similar projects.
