Abstract:In this study,the design strength of the deep cement mixing modifier and the unconfined compressive strength of the site modifier were compared and analyzed by the field application of deep cement mixing method.The strength reduction rate of modified marine soft clay should be used in engineering design analysis was given.

Keywords:soft clay;marine deposit;deep cement mixing method;unconfined compressive strength

1 概述

在沿海软土地基的各种工程建设中,以水泥作为固化剂的主要材料,通过深层搅拌机械将固化剂和地基土强制搅拌的深层搅拌法有着广泛的应用。(剩余2755字)
