摘要:
为了研究在下穿工程中管道沉降的问题,结合某地铁车站出入口通道下穿高压燃气管道工程实例,对Peck计算公式进行修正,采用数值模拟的方法验证修正的合理性,综合分析出入口通道下穿管道的安全性。研究结果表明:对于非圆形隧道,采用等效面积法计算地层损失,计算上部位移是合理的,可推知对经典Peck理论计算公式的修正是合理的,其计算结果与数值模拟结果相吻合,均可作为类似工程的参考方法。另外,大跨度暗挖施工下穿高压燃气管道危险性较高,不建议采用。
Abstract:
To study the problem of pipeline settlement in the underneath crossing engineering, combined with an engineering case of access passage with the underneath crossing highpressure gas pipeline in a metro station, the Peck formula was revised, and the rationality of the revision was verified by using the method of numerical simulation, then the safety of access passage with the underneath crossing pipeline was comprehensively analyzed. The results showed that for the noncircular tunnel, it was reasonable to calculate the ground loss by using the equivalent area method and thus calculate the upper displacement. It could be inferred that the revision of the classical Peck theoretical calculation formula was reasonable, and the calculation results were consistent with the results of numerical simulation, so both of them could be used as the reference methods of similar engineering. In addition, the risk of large span underground excavation construction with the underneath crossing highpressure gas pipeline was high, so it was not recommended.
