An on-site static load test of a reinforced concrete double-arch bridge with fracture is carried out, and a comparative analysis of the measured experimental results of the bridge working conditions and the calculation results of Midas/civil Finite Element Model is performed. The results show that the performance and structural deformation recoverability of the bridge is weak. The bridges overall load-bearing capacity does not satisfy its designed requirements.

In this paper, the application of finite element software with the actual structure of the field static load test for the engineering background, describes the space effect of portal frame under vertical load. Established a gymnasium mode of portal frame through the finite element software, quantitative analysis the space effect under the vertical load, and studied the spatial interaction of longitudinal anti-lateral component to the overall structure, and compared with the results of the field static load test. The calculation results show that, the reduction of spatial effect to internal forces under the vertical load should be considered in design. It is important that a reasonable increase in rigid tie and support can enhance the space effect of the whole portal frame.

Dynamic Load Test

Currently the bridge structure detections are mainly based on static load test and dynamic load test. The static load test has shortcomings of less test data, long time-consumption and high cost. However, the dynamic load test has the advantages of quick and convenient, its related technologies and theories are still not mature enough. To solve this problem, the detection of bridge structure based on quasi-static test is proposed in this paper. Quasi-static load is applied on the structure by moving the standard load vehicle slowly. Then create the structural finite element model and modify the model according to the measured data to make it consistent with the actual structure. The bridge actual structural mechanical properties can be acquired by conducting load test on the optimized structural finite element model. By doing this, the bridge safety could be evaluated quickly.

Abstract In order to realize the directional and controllable splitting of splitting grouting, the field grouting test was carried out. Using a new grouting pipe designed, the splitting direction and size of the branch vein are effectively controlled through the control of grouting pressure and grouting amount. In order to explore the bearing characteristics of split grouting pile and provide necessary parameters for the design of split grouting pile composite foundation in engineering practice, the field static load test and indoor geotechnical test of split grouting pile are designed, and the ultimate bearing capacity of single pile and necessary soil parameters are obtained. In order to make up for the limitations of field static load test, the three-dimensional finite element model of pile, soil and branch vein of split grouting pile is established by using the finite element analysis software ABAQUS. The finite element analysis results are compared with the measured values of field test, and the variation laws of pile shaft axial force, stress and displacement of branch vein at different depths, pile side friction, etc. are further explored, Through these changes, the interaction and load transfer mechanism between pile and soil are analyzed, which provides a reference for optimal design.

Most of the short span suspension bridges with steel truss girders early constructed will approach their design service life. Correctly evaluating the actual service performance is the basic basis of repairing, strengthening and technical reconstruction. First, load-bearing capacity evaluation based on static load test was briefly introduced. Then, combined with Chengnan bridge, the main existing damages and their causations of the bridge were summarized and analyzed. Based on the field detection datum and original design load grade, the finite element mode with some damages was established. Then, by analyzing the calculation results, the scheme of static load test was confirmed. Through comparing the static load test results with the results of upgraded finite element, the actual conditions of the existing bridge structure were evaluated. In order to resume its load-bearing capacity, some of measurements and suggestions of strengthening were proposed.

Based on the static load tests and stress tests results of two cases in Karsts area, the bearing behavior of piles were analyzed and compared in this paper, caves in the base of piles not only affect the base resistances, but also affect the frictions of piles. The finite element method was applied to analyze the influence of rocks in the base of piles on bearing capacities of piles, according to the calculated results; the modulus of rocks affects the bearing capacities greatly, bearing capacities increase with the modulus of rocks increasing.
