龙滩水电站右岸航道出口边坡施工期安全监测

边坡工程由于其地质条件的复杂性和变形机制的多样性，使得对边坡稳定性及其支护效果进行准确的预测和判断存在着很大的难度。而全面的现场监测和分析将为这方面的工作提供强有力的支持。根据龙滩水电站右岸航道出口边坡的监测设计、监测成果和开挖支护情况，分析了各段边坡变形和稳定状况，对加固处理措施和效果进行了初步评价。结果证明，航道出口边坡的监测为边坡工程施工和运行过程的安全提供了可靠的依据，经过一系列的加固措施的实施，边坡呈现比较稳定的状态，但仍需进行进一步的监测和维护。

Safety supervision on the exit slope of right waterway of Longtan Hydropower Station during construction period

It is difficult to forecast and judge the stability of slope and its support effectiveness because the complex geological conditions and diversified deformations. But all-round field supervision and analysis can give strong support to it. According to the monitoring design, results and excavation support of the exit slope of right waterway of the Longtan Hydropower Station, we analyze the slope stability and its deformation, and initially estimate the effectiveness of the slope reinforcement. Some conclusions were made as follows. The monitoring of the exit slope of right waterway has provided the construction and operation of slope with reliable basis. The slope reinforcement is relative stable. But it is necessary to conduct further monitoring and maintenance.
