水平荷载作用下整体式桥台桥梁受力性能研究

Study on Mechanical Properties of integral Abutment Bridges under Horizontal Load

整体式桥台桥梁近些年在国内外出现的越来越频繁,相比于传统的桥梁结构,其在提高桥梁的耐久性等方面发挥着极大的优势作用。以实际工程为背景和试验对象,对整体式桥台桥梁的受力性能进行了分析和研究,并通过与桩内应力试验实测值进行分析,得出在制动力的作用下,单侧桥台的受力相似于均匀温差下的受力。结果表明,P-y曲线法在分析整体式桥台桥梁水平荷载下的受力性能方面具有较好的可行性。

More and more integral abutment bridges in recent years at home and abroad, compared to the traditional bridge structure, in improving the durability and the bridge plays a role of great advantage.In this paper, the background of the actual project and the test object, the bearing performance of the integral abutment bridge is analyzed and studied.And through the tests of pile stress values were obtained in the analysis of power system under the action of force of unilateral abutment is similar to the uniform temperature difference stress.The results show that the P-y curve method is feasible on the mechanics property of integral abutment bridge analysis under horizontal load.
