O-Cell method with high safety and low cost has been widely applied in many projects compared with the conventional static load test, especially for high bearing capacity deep foundation. It has been applied in building, bridge, offshore wind power foundation, 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 circle type, rectangle type, bar-type, “L” type, etc. This paper introduces an application of O-Cell test in diaphragm, and the bearing capacity tested is the largest in the world at present with the maximum bearing capacity arriving at 313998kN. The O-Cell method is convenient to obtain maximum bearing capacity of large and deep foundation, an is helpful for designers to design the deep foundation reasonably and economically.
