摘　　要：介绍矩形地下连续墙基础竖向和水平荷载试验。通过对压浆前、后墙体的轴力传递、墙侧摩阻力和墙端阻力发挥特征的对比分析,揭示试验墙的荷载传递性状以及墙底注浆对其承载力的影响;水平试验得出了试验墙的水平临界荷载、水平极限承载力和地基土水平抗力系数的比例系数、墙身内力、墙身水平变形等。The vertical and lateral load test on rectangular diaphragm wall was introduced. By the constrastive analysis of axial force transfer,the exerting degree of shaft resistance and end bearing capacity between the part of the wall under the load case and the whole wall after grouting,the results indicates the effects of grouting on the bearing capacity and load transfer of the wall before and after grouting. By the lateral traditional static load test,the lateral critical load,lateral ultimate bearing capacity,the m-value of the lateral subgrade coefficient,internal force and the lateral displacement of the wall were calculated through analyzing the test data.
