INDOOR MODEL TESTS OF PLASTIC TUDE CAST-IN-PLACE CONCRETE PILE WITH SUPPORTING DISC

In order to study the effect of soil's consolidation and extrusion around the pile and pile tip in soft soil caused by sleeve setting to the stress on the bearing capacity of the TC pile with disc,the basic idea in this paper is provided with 4 different model pile setting in the model groove and compared to their carrying capacity. Through soil pressure gauge buried under the pile end and strain gauge next to pile lateral,we can get the settlement deformation law of the model pile under vertical load. We can also determine the time effect of single pile vertical ultimate bearing capacity,pile end resistance changes with the pile side resistance,load with load change and bearing capacity. Through the comparative analysis of the test results of different test of pile,we can get the timeliness of research with stress plate bearing capacity of TC pile.
