浅谈测绘技术在大机精确法施工中的应用

随着我国铁路事业的不断发展,传统的施工方法已经不能满足当今高速重载的列车对于线路质量的需求,为了应对这一情况,路局提出了大机精确法施工的建议。本文叙述了利用GPS全球卫星定位系统测绘铁路线路为大机精确法提供起、拨道量数据,全面整治线路方向、漫洼,从而提高线路质量。

Researches on the key technology and equipment for rapid construction of long tunnels with large section

Excavation and lining are two main important tasks in tunnel construction. Conventional sequential operations may not be appropriate due to time limit for a project and the high cost of construction. The authors developed a new mode of tunnel construction that excavation and lining can be operated simultaneously. The new mode of tunnel construction has been successfully applied to Dahuofang Water Conveyance Project in Liaoning Province. This paper makes a comparison of Main Beam TBMs and Double Shield TBMs used in Dahuofang Water Conveyance Project, and the features of Full-ring Inner-through Lining Shutter Jumbo which solves the problem of interference between excavation and lining.
