| 摘 要： | 舟山大陆连岛工程西堠门大桥为一主跨跨度1 650 m的悬索桥,其北塔位于海中的老虎山上。老虎山四周临空,山体单薄,缓倾坡外裂隙构成边坡稳定的潜在底滑面,尽管塔基所在工程边坡整体稳定,但浅表部存在不稳定块体。本文对浅表部边坡进行了在最不利工况下的定量计算和分析,并提出对边坡所在最低海水位以上浅表部岩体进行框架梁锚索和锚杆加固方案,加固后工程边坡稳定性系数都在1.5以上,满足工程安全要求。

| Abstract: | The Xihoumen Bridge is a rope-suspension bridge with span of 1650m,in Zhoushan Island-Mainland Link Project.Its north tower is located at the Laohushan mountain in the sea.Laohushan mountain is isolated by sea,and the gentle inclination joints form the slope's potential sliding face,which causes the mountain slop loses its stability,Though as a whole project the slope of the base of the tower is steady,the shallow part of the slope is unstable.This paper does the calculation and analysis to shallow side slope in the condition of the most unfavorable state of the project,and suggests using the project of frame set-roof beam anchor wire and anchor pole to strengthen and deal with the shallow rock body of slope slide potential,so that the slope stability coefficient can reach to above 1.5,and can attain to the safe demand of the project. |
