In order to get its partial stress value and distribution as well as its force transfer path,prestressing tendons and main cable was simulated by spatial cable element,concrete anchor beam was simulated by 3D block element,and a 3D refinement finite element model was established with secondary development technology based on the platform of general finite element program.

This paper intends to introduce the operation regulations of anchorage beam static pressure pile issued by the Company itself and put forward some suggestions of how to solve the problems concerning design, construction, testing and quality inspection as well as the innovation of construction plant.

The distribution of ring pre-stress, anchoring steel beam and pre-stress, vertical pre-stress of the anchoring zone of the main tower in Songhuajiang cable stayed bridge are introduced and the corresponding construction technologies are clarified in the paper.

Finite element analysis on ultimate bearing capacity of high-pile wharf crossbeam

Besides,conclusion that bolt counterforce device is only applicable for piles of small tonnage can be reached and load cell method is recommended for large tonnage.

In this paper videotaping the property of engineering geology in karst area,a bolt counterforce device is proposed for the pile static test based on the comparative studying the accommodation of the different traditional loading test devices.
