| Abstract: | The concrete bore pile deformation and side friction of pile on dead-load test under 16000kN is analyzed.The pile length,concrete strength grade and proportioning are determined by stratum condition,bearing capacity,strength and construction method.The bearing capacity of single pile,the transitive rule of the endogenetic,the sedimentation on the top of the pile and the deformation of the pile are determined through test. |
| |
| Keywords: | concrete strength grade steel stress detector pile endogenetic side friction of pile elastic distortion of the pile |
