Development of a New Soft Ground Improvement Method Using Pore Water Suction and Overburden Load

Introduction of the improvement principles, operation methods, and improvement effects of a new soft ground improvement method.

This document summarizes the development of a new soft ground improvement method using pore water suction and surface load application. The Super Well Point method (SWP) is an improved version of the vacuum deep well technique, which allows for the efficient drainage of pore water from various types of ground, including cohesive soils, by separating and suctioning pore water and air within the ground. Using this SWP method, we have developed a technique to promote the settlement of soft cohesive soil layers and improve soil properties. As a result of the improvement, applying this method to alluvial cohesive soil layers and introducing air temporarily caused ground uplift, and continued suctioning led to accelerated settlement.
