某公路和水渠下穿既有京沪高铁桥梁,交叉处地面挖深较大,下穿高铁处均采用防护桩支护后顶进U型槽的方案。建立有限元模型对施工过程进行影响分析,结果显示:预制U型槽基坑布置于高速铁路影响区外;施工中高铁桥梁墩顶竖向、纵向和横向的最大附加位移值分别为1.49、0.99和0.75 mm, U型槽顶进至桥下设计位置时对桥梁墩顶竖向位移的影响最大;工程实施对桥梁桩基承载力的累计影响小于原设计单桩容许承载力;分析结果满足《公路与市政工程下穿高速铁路技术规程》的相关要求。 相似文献

Seismic Responses of Asymmetric Base-Isolated Structures under Near-Fault Ground Motion 总被引:1,自引:0,他引:1
An inter-story shear model of asymmetric base-isolated structures incorporating deformation of each isolation bearing was built, and a method to simultaneously simulate bi-directional near-fault and far-field ground motions was proposed. A comparative study on the dynamic responses of asymmetric base-isolated structures under near-fault and far-field ground motions were conducted to investigate the effects of eccentricity in the isolation system and in the superstructures, the ratio of the uncoupled torsional to lateral frequency of the superstructure and the pulse period of near-fault ground motions on the nonlinear seismic response of asymmetric base-isolated structures. Numerical results show that eccentricity in the isolation system makes asymmetric base-isolated structure more sensitive to near-fault ground motions, and the pulse period of near-fault ground motions plays an import role in governing the seismic responses of asymmetric base-isolated structures. 相似文献
