工作面稳定性是在松散砂层中开挖时必须考虑的一个特别重要的因素。如果能确定工作面稳定性，将成为隧道规划和安全的重要指标。本报告的目的是从地面的动力特性和物理特性两方面考察工作面稳定性，并根据从果部河隧道合同中收集的调查、试验和测量数据，确定工作面稳定性的标准判断。果部河隧道合同位于松散的砂层中，土壤条件不能提供足够的工作面稳定性。
Face stability is a particularly important factor that must be considered when tunneling in loosen sand layers. If face stability can be determined, it will be an important index for tunnel planning as well as safety.The purpose of this report is to examine face stability in view of both the dynamic and physical properties of the ground and to stady standard judgements of face stability based on investigations, tests and measuring data collected from the Kokubu River Tunnel contract which was in a loosen sand layer in which the soil condition offered insufficient face stability.
