峡谷区 meaning in English
canyon country
Examples
- At the same time watertight rock surround the carbonate rock , which is helpful to water percolate deeply and trigger earthquake
同时，峡谷区碳酸盐类岩石周围又有弱透水和微透水的岩层包围着，有利于库水向深部渗透，诱发地震。 - The 6 regions , including the contiguo us areas of southwest sichuan and northwest yunnan , the west part of sichuan , th e contiguous areas of sichuan , guizhou , hubei and hunan etc . , should be conside red as the key ones for conservation in the yangtze basin
川西南滇西北、川西高山峡谷区、川鄂湘黔接壤区、南岭山地北部6个区域成为长江流域自然保护的关键区域。 - Based on geochemical technical tests conducted in the yanzidong ore block , western yunnan , the authors used the hydrochemical survey as the grade 3 inspection method for high canyon target areas , and rearranged the methods for routine stream sediment survey and soil survey
摘要根据在滇西燕子洞矿段的化探方法技术试验研究结果，将水化学测量作为高山峡谷区靶区三级查证的方法，并对常规水系沉积物测量、土壤测量的工作方法进行了调整。 - Although the empirical formula ? = yh [ 14 . 7 ( rwrlogd ) + 3 ] has been applied successfully to some engineerings , but it is a general formula , not one specially for rocky bank slope in gorge area . so the author constructs a statistical formula smr
71n (只log0 ) + 13 ]在工程实践中的应用效果较好，但该公式是建立在大量统计资料上的通用公式，并不专门针对峡谷区桥基岸坡，因此作者基于smr方法，统计拟合出适用于峡谷区桥基岸坡的经验公式?夕： 2 - Depending on how the ground surface is denuded , the feature of the current crustal stress field and rock stress environment can be calculated analyzing the result in this paper : by analyzing the recovering feature of the elastic deformation of the rockmass in unload - stage under various pressures , it has been found there is close relationship between the recovering degree of the elastic deformation of the rockmass and the unloading degree of the pressure the direction of the major principal stress in the crustal stress field is not consistent with the direction of the crushing stress regional tectonics borne during the last tectonic movement . the evolving degree of the regional geomorphology evidently affects the current crustal stress field , which changes from the self - weight stress field to the horizontal stress field , with the changing of the eroding degree of the regional geomorphology ranging from valley area to hilly country to flat country . in valley area , where there is two stress belts , the bankslope s tress belt and the self - weight stress belt within the mountain . the direction of the major principal stress is nearly parallel to the ground surface and inclines towards the valley in the bankslope stress belt . it is nearly vertical in the self - weight stress belt
通过本文的研究成果，根据区域性地貌的演化特征，我们可以大致地对现今地应力场进行判断：在分级卸荷条件下，岩体中弹性变形的恢复具有明显的规律性，这种规律对于研究地应力场的演变是有帮助的；地应力场中最大主应力方向与区域构造形迹在最近的构造运动中所受区域性挤压应力的方向无明显的对应性；区域性地貌形态的演化程度对现今地应力场的特征具明显的影响，随着区域性地貌侵蚀程度由峡谷区、丘陵区、平原区的变化，现今地应力场特征由自重应力场、水平应力场为主含少量自重应力场特征向水平应力场的规律变化；在峡谷区，山体中具有两个应力带：自重应力带和卸荷应力带，最大主应力方向在卸荷应力带中近平行于坡面并倾向于河谷、在自重应力带中近于直立；根据原始地面遭剥蚀的程度，可以大致地估算最大主应力和中间主应力的量值和方向；在丘陵区和平原区，最大主应力的方向近于水平，并与附近区域性侵蚀盆地和河流的展布方向基本平行，根据原始地面遭剥蚀的程度，可以大致估算其最大主应力的量值；根据区域性地貌形态的特征来分析工程区的现今地应力场特征，并进而大致了解岩石的应力环境，这种分析方法得出的结论与许多实际的地应力测试成果基本一致，对于大型水电工程地下厂房和压力隧洞的设计是有所帮助的。
