Research and Application of Stress and Strain Testing Method for Plain Concrete Pile

At present, the stress-strain test of pile body mainly focuses on precast and cast-in-place with reinforcement, this is because pre-assembly components can be carried out in or reinforcement cage before prefabricated formed. When formed, it could embedded together cage. But for plain concrete field research report rare. In view shortcomings existing methods piles, resistance strain gauge inclinometer are improved to realize their application which employed deformation characteristics under horizontal load. The results show applicability method, provides useful references similar research.
