摘要
地上桥梁与地下隧道同位建设时,需同时满足桥梁和隧道两种构筑物的安全和使用需求,需要对同位分合建的关键问题进行分析研究,以合理选择分合建方案。以某穿越城区的高速公路项目为工程背景,对桥隧同位布置的四种可能方案进行分析,研究了不同方案的结构受力对项目总体方案和既有水系的影响,工程造价与节能与环保效果,经综合对比分析,得出桥梁采用桩基础与整体式隧道合建为推荐方案,其受力明确、节约用地的特性契合交通节能、低碳环保的理念。
When overground bridge and underground tunnel are constructed at the same position,the safety and use requirements of bridge and tunnel should be met at the same time,and the key problems of the design scheme of the joint construction at the same position should be analyzed and studied to select the joint construction scheme reasonably.This paper analysed four possible schemes for the arrangement of bridges and tunnels at the same position in a certain urban expressway project.By studying impact to overall plan of the project and the existing water system,construction cost and energy saving and environmental protection effects of the structural stress of different schemes,with the comprehensive comparison and analysis,a bridge pile foundation and integral tunnel was selected as the recommended scheme,whose characteristics of clear force and economical use of land are in line with transportation energy saving and low carbon environmental protection concept.
