摘要
结合具体工程实例,分析了跨既有线深基坑防护的技术难点,进行了防护方案比选,详细介绍了防护方案的设计,指出该方案实施后有效地保证了既有路基边坡的稳定和既有线安全运营,保证了承台顺利开挖。
Combined with specific engineering examples, the technological difficult of haven built railways deep excavation retaining scheme was analyzed, and retaining plans were compared selection. The retaining plan design plan was introduced detail. It pointed that the plan made sure built railways side slope was stability and run safely, and platform switched smoothly.
