Tóm tắt:
O-cell method with high safety and low cost has been widely applied in many projects compared with the conventional static load test. It has been applied in building, bridge, etc. The load- displacement curve of O-cell test could be well converted into conventional pile top load-displacement curve. Based on different deep foundation styles, the load cell could be manufactured into different types. The maximum diameter comes up to 8m, the maximum bearing capacity arriving at 313998 kN. The O- cell method is convenient to obtain maximum bearing capacity of large and deep foundation, helpful for designers to design the deep foundation reasonably and economically. Besides, the O-cell test also could be well to inspect the quality of pile base and grouting quality.
