硬岩隧道掘进机完成掘进的预计时间 ,对估算标价来说是一个关键问题 ,特别是劳力成本、经常费和材料设备的投资 ,都取决于工期 ,并极大地影响造价。而且 ,如果延长了工程的交付日期 ,违约罚金是很高的。在确定工程造价中的一个主要任务是 ,预测隧道掘进机的掘进速度。施工准备?
The estimated time to complete tunneling of a hard rock tunnel boring machine is a key issue in estimating the price. In particular, labor costs, recurrent costs, and investment in materials and equipment depend on the duration of the project and greatly affect the cost. And, if you extend the delivery date of the project, the penalty for the penalty is high. One of the major tasks in determining project cost is to predict the tunneling speed of tunnel boring machines. Construction preparation?
