2.13年7月10日四川省汶川县绵虒镇降持续性暴雨,促使簇头沟暴发降雨频率为2.的泥石流,导致岷江堵塞,严重威胁沟口居民及下游安全。以簇头沟的1∶10000等高线、2.13年降雨数据与遥感影像等作为基础数据,结合野外考察资料,运用FLO-2.软件,模拟计算簇头沟在不同降雨频率下(5%、2.和1%)泥石流的运动堆积过程,研究簇头沟泥石流的危险性。在2.降雨频率(实际降雨频率)条件下,模拟得出最大泥石流流速为12.99m/s,最大泥石流泥深为15.7 m,堆积面积为9.55×10~4.^2.与实际堆积范围进行验证,精确率为77%,在合理误差范围内,成果可靠性高。通过泥深与流度来构建泥石流的强度模型,再与暴发的重现周期相结合而构建簇头沟泥石流危险性评价模型,获得堆积扇危险范围分布图,其中高危险面积占61%,中危险面积占19%,低危险面积占2.%。为簇头沟泥石流的灾害防治提供科学的参考依据。

Interferometric synthetic aperture radar (InSAR) is a potential earth observation approach, and it has been demonstrated to have a variety of applications in measuring ground movement, urban subsidence and landslides. Currently InSAR provides the ability to map accurate DEM and measure ground deformation to sub-centimeter accuracy. However, many factors affect InSAR to measure ground movement since dam constructions are built in a large scale area with a complicated climate and unstable geology. This paper discusses potential applications of integrated InSAR and GPS to monitor a large-scale ground movement due to hydropower developments. The integration of InSAR and GPS can provide a cost-effective means for monitoring deformation of hydropower developments. Moreover, two novel methods, both the improved spatial interpolating method and estimation of 3D surface motion velocities method, are proposed and the experimental results and analysis are given in this paper.

以康苏2..30 m岩石地温监测结果为基础,分析观测点的应震特征,结果表明,岩石地温的前兆异常主要以短临震前异常为主,具有很好的重复性。主要特点包括:4.地震震前特征为高频突跳及温度的快速下降-持续-上升至背景值,地震往往发生在异常结束的5~30 h内;6级地震主要发生在温度的快速上升或下降变化后的异常持续中,高频出现在震前12.d前,且高频持续时间短。初步分析认为,观测点温度的异常特征主要与其地质构造环境及地下流体的参与密切相关。
