深基坑栈桥支撑结构设计与实践
摘要:工程中由于基坑面积大、深度深,且形成内支撑形式的支护体系,致使基坑土方开挖难度特别大,因此,首道支撑体系结合栈桥的结构设计与应用势必成为一种支护结构形式。通过总结栈桥结构设计的常见形式,根据建筑结构设计原理,对作为内支撑栈桥结构构件的整体受力情况进行分析,并结合工程实例介绍了深基坑栈桥支撑结构的设计方法,为栈桥支撑结构设计提供一些参考。
Abstract:Because the deep-foundation-pit and the depth in the project, and it forms the supporting system of internal bracing. It makes the earthwork excavation to be speeially extremely difficult. Therefore, the first supporting system will com- bine structural designs and application of the trestle bridges. It will become the structural styles inevitably. The article based on the building structural design principles, carried on the analysis of the overall stress situation of the supporting system of inter- nal bracing through summaring the common form of trestle bridge structure. Combined with the projeet example, the design methods of supporting system of trestle bridge braeing construction in deep-foundation-pit is introduced, It provided some ref- erences for the structural designs of trestle bridge bracing.
