天生桥一级电站大坝的安全监测设计和监测仪器埋设

天生桥一级电站大坝是国内在建的最高混凝土面板堆石坝。本文简要介绍了大坝的安全监测设计，特别提到了具有特色的几项，其中如测堆石体沉降和水平位移的管线长３５０ｍ的垂直水平位移计，这是当今世界上堆石坝最长的已埋设管线。叙述了大坝安全监测实施的４个阶段及各个阶段要做的工作。文中还谈到了为保证大坝安全监测仪器埋设成功有４个方面的工作需要做好。

SAFETY MONITORING DESIGN AND INSTRUMENT INSTALLATION IN CONCRETE FACE ROCKFILL DAM OF TIANSHENGQIAO FIRST CASCADE (TSQ-1) HYDROPOWER STATION

The dam of TSQ-1 hydropower station is the highest concrete face rockfill dam (CFRD) under construction in China.This article briefly describes the dam safety monitoring designs,especially several characteristic items,such as hydrostatic settlement cells and horizontal displacement gauges,which measure the settlements and horizontal displacements in the rockfill,and the longest pipeline ever installed in rockfill dams throughout the world,which is up to 350 m in length.Four stages are described in dam safety monitoring design and implementation,and the work which needs to be done at each stage is also described.Four aspects of work which are needed for full implementation in CFRD of TSQ-1 hydropower station are introduced.
