从事隧道开挖工程的承包商是在复杂和危险的环境中进行工作。在安排施工计划和编制预算中,地层的性质常常是一个无法预测的因素。但是,有另外一些方面可以进行精确的评价,以限制超越隧道工作者的控制范围外的主观臆测因素。这就是引进计算机分析的理由。 Contractors engaged in tunnel excavation work in complex and dangerous environments. The nature of the formation is often an unpredictable factor in scheduling construction and budgeting. However, there are other areas where an accurate assessment can be made to limit subjective assumptions beyond the control of tunnel workers. This is the reason for the introduction of computer analysis.
