Manual-excavation concrete pile is generally designed as foundation of urban high buildings.So,it is very important to determine the load-bearing capacity parameter of pile end soil.Taking the foundation engineering of a certain residential plot in Hunan as example,this paper discusses and analyzes how to adopt deep plate loading test to determine the of load-bearing capacity of pile end soil of manual-excavation concrete pile,and gives some suggestions to the application of deep plate loading test.The result of the test indicates that the deep plate loading test can exactly test the ultimate load-bearing capacity of pile end soil.
