摘要
以兰州市轨道交通1号线一期工程迎门滩站项目为例,对比分析了大跨度深基坑多种支护设计方案的优缺点,并通过受力分析与理论计算,论证了混凝土支撑与钢支撑混合支撑的形式可以满足支护要求。根据施工实践,着重介绍了混合支撑施工的控制重点,对类似工程具有一定的借鉴意义。
Taking the Yingmentan Station Project of the first phase of Lanzhou Rail Transit Line 1 as an example, both advantages and disadvantages of various support design schemes for large-span deep foundation pits are compared and analyzed. Through the force analysis and theoretical calculation, the combined type of concrete support and steel support can meet the support requirements. Based on the construction practice, the key points for controlling the hybrid support construction are emphatically introduced, which have certain reference significance for similar projects.
