過蝕谷
英文
overdeepened valley-
The first power station of jinping mountain lies in the west section of the yanglongjiang river from santan to shoupagou gully, with a double - curved arch dam of 305 - meter height and a normal water storage of 1880metres. the exposed strata of the damsite are marbles and arenaceous rocks of triassic and solution fissures have been developed in the marbles of the left - bank ' s dam abutment, and they have become a stratum of strong leakage. as a result, it has been an important problem for the dam foundation to stop leakage
錦屏一級電站位於西雅礱江的三灘至手爬溝河段，壩型為305米高雙曲拱壩，正常蓄水位標高1880米。壩址區出露的地層為三疊系雜谷腦組二段大理巖和三疊系雜谷腦組三段的砂板巖。在勘探過程中，發現左岸壩肩大理巖體中的構造裂隙和溶蝕裂隙發育，且成為強滲透地層，為此壩基的防滲成為重要問題。But then, with the intention of bringing trees back to the territory, serious efforts were made by the government to green the countryside. however, the hills - and even some valleys - were dominated by badlands and erosion scars
不過，當年的山嶺，以至部分山谷，皆遍布劣地和侵蝕遺痕加上這崎嶇不平之地主要由花崗巖組成，表土養分易於流失，凡此種種，都對植樹工作構成嚴峻的考驗。The mechanical genesis of the complicated rock mass is because several times of tectonism in pro - period made the structure of rock mass in the right dam foundation damaged seriously and rock mass alteration made its mechanical character more anisotropy. after that the fractures in the right dam foundation slope were stretched at the beginning of the quaternary period because in the period yakouhoushan mountain quaquaversal dome was blowups quickly. at the same time, the valley trenching of lancang river reach to 800 - 1000 meter in altitude at the right bank in nuozadu dam site
導致右岸巖體復雜化的成因是，右岸巖體在早期遭受了多期構造作用和巖體蝕變的基礎上，第四紀早期丫口後山穹隆的快速隆起與當時河谷下切至800m 1000m高程這一特殊因素組合引起了右岸巖體沿原有的斷裂（裂隙）張開，使地下水等風化營力能夠到達坡體較深部位，經過長期的風化卸荷作用，形成了右岸復雜巖體。It will lengthen as a result of headwater erosion and, thereby, will cut a valley through both hard and soft rock.
由於向源侵蝕的結果，它不斷延長並且穿過軟硬巖石從中切出一條河谷來。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
通過本文的研究成果，根據區域性地貌的演化特徵，我們可以大致地對現今地應力場進行判斷：在分級卸荷條件下，巖體中彈性變形的恢復具有明顯的規律性，這種規律對于研究地應力場的演變是有幫助的；地應力場中最大主應力方向與區域構造形跡在最近的構造運動中所受區域性擠壓應力的方向無明顯的對應性；區域性地貌形態的演化程度對現今地應力場的特徵具明顯的影響，隨著區域性地貌侵蝕程度由峽谷區、丘陵區、平原區的變化，現今地應力場特徵由自重應力場、水平應力場為主含少量自重應力場特徵向水平應力場的規律變化；在峽谷區，山體中具有兩個應力帶：自重應力帶和卸荷應力帶，最大主應力方向在卸荷應力帶中近平行於坡面並傾向于河谷、在自重應力帶中近於直立；根據原始地面遭剝蝕的程度，可以大致地估算最大主應力和中間主應力的量值和方向；在丘陵區和平原區，最大主應力的方向近於水平，並與附近區域性侵蝕盆地和河流的展布方向基本平行，根據原始地面遭剝蝕的程度，可以大致估算其最大主應力的量值；根據區域性地貌形態的特徵來分析工程區的現今地應力場特徵，並進而大致了解巖石的應力環境，這種分析方法得出的結論與許多實際的地應力測試成果基本一致，對于大型水電工程地下廠房和壓力隧洞的設計是有所幫助的。This theme selected weihe river round tianshui, jinhe river round binxian, bahe river round lantian and luohe river round luochuan to study the evolutionary model of river terraces in the mid - tail of weihe river. we have built the cross - section of each river, and analyzed the evolution of each river terrace in the mid - tail of weihe river according to the velocity of downcuting and lateral erosion
本論文以天水渭南鎮段渭河、彬縣段涇河、藍田段灞河和秦家河段洛河為例建立渭河中下遊河流階地演化模式，以階地形成年代為標尺，根據下切速度和側蝕速度對渭河中下游各河谷階地的演化過程進行了分析。Abstract : because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone, its ecological environment is very fragile. based on the fragileeco - environmental, the coal mining and construction have brought out some new environmental problems. man - made debris flow problems is the most serious of them which caused by coal mining, construction of railway and highway as wellas exploiting stone. through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site, the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully. at present, this experiment method is the best way to analyze debris flow genesis and process
文摘:神府東勝礦區位於黃土高原北部乾旱半乾旱過度地帶，由於煤田的大量開采，誘發了大量的環境問題，尤以人為泥石流最為嚴重.本文以神府-東勝礦區人為泥石流為研究對象，採用人工放水沖刷模擬實驗的方法，分析了坡面型和溝谷型泥石流源地鬆散體起動、產沙、泥石流過程的特性，所得結論為: （ 1 ）放水歷時長、強度大，有利於泥石流的形成; （ 2 ）棄土石渣易起動，是該區泥石流固體物質的主體; （ 3 ）溝道型泥石流放水沖刷模擬實驗，便於觀測泥石流的全過程，坡面型泥石流放水沖刷模擬實驗，利於統計產沙、觀測侵蝕形態Because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone, its ecological environment is very fragile. based on the fragileeco - environmental, the coal mining and construction have brought out some new environmental problems. man - made debris flow problems is the most serious of them which caused by coal mining, construction of railway and highway as wellas exploiting stone. through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site, the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully. at present, this experiment method is the best way to analyze debris flow genesis and process
