TEST AND RESEARCH ON THE BEARING BEHAVIOR OF RECTANGULAR DIAPHRAGM WALL

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.
