为了缩短长隧洞施工工期，需增加工作面，一般常用偏洞或斜支洞来实现“长洞短打”的目的。而引冯济羊输水隧洞工程深穿黄土沟壑区，根据地质、地貌特点在施工中采用了百米竖井、谷底斜井导洞方案，以缩短工期，节省投资。监理工程师根据实际情况在导洞方案设计、施工技术、机械选型诸方面提出了切实可行的合理化建议并在工程监理中积累了经验。不但加快了工程进度、节省了投资，而且工程质量及施工安全都得到保证。
In order to shorten the construction period of long tunnels, it is necessary to increase the working face and commonly used partial holes or oblique holes to achieve the purpose of “long hole short beating.” The Fengjian Yang water diversion tunnel project runs deep into the loess gully area. According to the geological and geomorphological features, a 100-meter shaft and a guide tunnel at the bottom of the valley were used to shorten the construction period and save investment. Based on the actual situation, the supervision engineer put forward feasible and reasonable suggestions in the design, construction technology and mechanical selection of the guide tunnel and accumulated the experience in the project supervision. Not only speed up the progress of the project, saving investment, and project quality and construction safety are guaranteed.
