土石坝上游坝面受水冲刷,容易引起坝面垫层脱空,水蚀等病害问题,基于地质雷达技术对上游坝面探测并分析回波幅值信息可及时发现并判断隐蔽部位病害的位置与类型.本文通过数值正演方法研究地质雷达在混凝土面层与垫层的界面反射特征与规律,通过提取回波幅值,建立垫层相对介电常数与回波幅值的数理关系;并将该数理关系应用至某土石坝的上游坝面病害探测与分析,达到了精准快速识别上游面板及防水织物破损位置及其类别的目的.得
太阳耀斑是太阳活动最剧烈的一种爆发现象,当太阳耀斑发生时,将辐射出大量的X射线和高能粒子等.X射线约8.3 min最先到达地球,引起电离层的电子浓度急剧增大,使得电离层的等效反射高度随之降低,从而引起甚低频信号的相位异常变化,而且会引起短波通讯中断.高能粒子约1～3天后到达地球,造成高纬度地区的雷达和无线电通讯的骚扰,甚至信号中断,同时对宇航员的身体健康也会造成伤害.本论文在河南新乡地区用甚低频接
地下介质的黏性吸收作用会造成地震波时域波形扭曲,高频能量损失.忽略黏性因素的理论研究成果难以应用到实际工作中.因此,在黏性介质中开展薄互层正演模拟研究更具实际意义.本文基于波动理论,引入与黏性吸收有关的复速度,利用波动方程对不同黏性、不同互层数、不同单层厚度的等厚薄互层进行正演模拟.采用广义S变换分析零偏移距地震道反射复合波的瞬时频谱.研究发现:当时域波形可分时,时域波形与互层数具有一一对应关系,
We analyzed the spatial local accuracy of land cover(LC) datasets for the Qiangtang Plateau, High Asia, incorporating 923 field sampling points and seven LC compilations including the International Ge
The risk posed by natural disasters can be largely reflected by hazard and vulnerability. The analysis of long-term hazard series can reveal the mechanisms by which risk changes. Drought disasters are
The lake hydrological and meteorological data of the Tibetan Plateau are not rich. This research reports the observed climatic data and measured water levels of saline lakes from the local meteorologi
The special geography and human environment of the Qinghai-Tibet Plateau has created the unique hydrochemical characteristics of the regions natural water, which has been preserved in a largely natura
石漠化是发生面积仅次于沙漠化的荒漠化类型,已成为中国西南喀斯特山区可持续发展的主要障碍,其治理与恢复是复杂的系统工程。从治理技术层面,以1 159组简单专利族为数据基础,揭示国内石漠化治理技术类别分布和主要领域。在对专利进行简要计量分析以提供概貌认识的基础上,通过阅读专利摘要内容,采用自下而上的聚类方法将当前专利划分为石漠化判断、治理、产业经济3个大类,监测与评价、科研仪器、生物治理、工程治理、化
Land use patterns arise from interactive processes between the physical environment and anthropogenic activities. While land use patterns and the associated explanatory variables have often been analy
