Abstract This study presents the results of full-scale tests and three-dimensional finite element analyses of deep cement mixing (DCM) and stiffened deep cement mixing (SDCM) columns under lateral loads and DCM and SDCM walls under deep excavation in soft clay. The DCM walls used in this study comprised one, two and three rows of DCM columns, whereas the SDCM walls consisted of only one row of DCM columns with steel H-beams inserted in either all DCM columns or in alternating DCM columns. The measured and simulated results are presented in terms of profiles of lateral displacement, settlement and bending moment.

SDCM 和 DCM 墙体在软粘土深挖下的性能：现场测试和 3D 模拟

摘要 本研究介绍了在横向荷载作用下的深层水泥搅拌 (DCM) 和加筋深层水泥搅拌 (SDCM) 柱以及在软粘土深基坑开挖下的 DCM 和 SDCM 墙体的全尺寸试验和三维有限元分析结果。本研究中使用的 DCM 壁包括一、二和三行 DCM 列，而 SDCM 壁仅由一行 DCM 列组成，钢 H 梁插入所有 DCM 列或交替的 DCM 列。测量和模拟结果以侧向位移、沉降和弯矩的剖面呈现。
