So sánh sự thay đổi về cường độ chịu nén và tính biến dạng của nền ở vùng Đồng bằng sông Cửu Long khi xử lý nền bằng trụ đất xi măng với nền tự nhiên

Abstract

The subsoil in the Mekong Delta region is mostly soft clay, organic clay or mixed clay mud with deep thickness which makes the works are of low stability and low bearing capacity. In current popular soft ground treatment solutions, deep cement mixing method is considered as a solution with many characteristics suitable for the soft soil treatment. To contribute more information and reference data for the calculation of deep cement mixing piles in Mekong Delta Region, this research compares compressive strength and deformation values of deep cement mixing collumns with samples through unconfined compression test and combining with computation using Plaxis 2D software.
