摘要
本文以引黄工程为例 ,对两种施工方法 ,从破岩理论、进度、质量安全、经济等有关方面进行了比较 ,针对不同工程 ,如何正确选用施工方法 ,作者提出了自己的看法。
In this paper,the YRDP is takes as an example,two construction methods,namely the “drill-blast” method amd the TBM method,are compared each other in many fields such as the theory of crushing rock,the construction progress,the quality and the safety in construction and the economy.The conclusion is that the TBM method is of the quicker construction speed,higher degree in safety,less disturbance on the surrounding rock and less influence on the surrounding structure than the “drill-blast” method.As for the economy,the writers hold that the cost using the TBM may be almost equal to that using the “drill-blast”method provided that the corresponding measures are adopted.Finally,the writers suggest that when the tunnel is relatively long and has complicated geological condition,the TBM method should be firstly adopted.
