某隧道盾构法施工由于地处富水砂层的复杂地层,所以在测算出盾构机承载力足够的情况下,施工单位在盾构机推进到选定位置后,通过实施一系列措施配合精密的测量保证了盾构在复杂高含水的软弱地层顺利停机。着重介绍了停机过程中的风险和处理措施,以及监测和应急措施等关键技术。
Construction of a tunnel shield construction is located in a complex formation of water-rich sand, so in the calculation of sufficient shield bearing capacity of the case, the construction unit in the shield machine to promote the selected location, through a series of measures to support Precise measurements ensure the smooth shut down of the shield in the complex, high-water and weak areas. It highlights the risks and measures during downtime, as well as key technologies such as monitoring and emergency measures.
