| 摘 要： | 江阴长江公路大桥建成后将是主垮1385m,总长2888m 的大型悬索桥。本文在对大桥桥址区域地震地质和区域地震活动、桥址区地震构造条件及其断裂活动性综合研究的基础上,用概率方法对桥址区进行地震危险性分析;并结合桥址两岸不同的岩土条件,大桥塔墩和锚锭部位局部地形地貌、地下介质的横向非均匀性,绘出了大桥塔墩和锚锭场地不同土层的设计地震动工程参数。为大桥的抗震设计提供了可靠的科学依据。

| Abstract: | The parameters of designed seismic shaking are presented for the different layers of soil of
tower pier and anchorage sites in the highway bridge over Changjiang in Jiangyin to provide
the reliable basis for aseismic design for the bridge,hased on the comprehensive study of seis-
micity,seisniotectonies and fractural activity in the region of the bridge site and combining
with the difference of the geotechnical condition in hanks,the local relief of tower pier and an-
chorage area and lateral inhomogeneity of underground medium,and seismic risk analysis ob-
tained by probability method. |
