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。Based on the bedding features of weak intercalations in sandstone plates near the top of underground cavity, the probable failure scale of bedding sliding, the probable settlement, the folding places and the critical length of sandstone beams are computed seperately, then the stability of underground cavity is analysed
針對地下工程頂部層狀砂巖中存在順層發育軟弱夾層的情況，分別對開挖后可能出現的層間滑動破壞范圍、巖板的沉降、折斷和臨界長度進行計算，並分析其穩定性。Main factors and mechanics influencing water inrush from roof snadstone
影響徐州礦區煤層頂板砂巖涌水的主要因素及機理In the thesis, sand packed glass plate model was applied to physical simulation of the macroscopic throats forming mechanism, studied effects of these factors as sedimental characteristics, petrophysical property, production process etc. on the forming of macroscopic throats
摘要動用填砂玻璃板模型對疏鬆砂巖油層大孔道形成機理進行物理模擬，探討了沉積特徵、油層物性、開發過程等因素對大孔道形成的影響，歸納了大孔道形成的因素模型及大孔道形成過程中的產量壓力特徵。A brief introduction is given to the treatment of the zeya dam foundation, principles of seepage control and design of the concrete face rockfill dam of the zeya reservoir. as for the excavation of the sand - gravel zones, except the toe slab and its 1 / 9 bottom width down stream, the alluvial layers are excavated to the micro - weathered rocks, while the other sections remain unexcavated. regarding to the treatment of the fracture zones, concrete filling is used for the toe slabs and semi - permeable materials are used for other section. according to the construction characteristics, a filter is placed in the down stream embankment foot. to improve the integrity of the dam foundation and anti - seepage capability consolidation grouting and curtain grouting are adopted. as a result safety, economic benefit, convenience in construction and good performace are achieved
簡要論述澤雅水庫面板堆石壩壩基處理和防滲的原則及設計要點.趾板基礎和堆石體各區砂礫石基礎開挖，除趾板與其下游1 / 9底寬范圍以及壩腳挖除沖積層至弱風化（局部微風化）基巖外，其餘部分均予以保留.斷層破碎帶處理，趾板部位採用混凝土塞，其它部位採用半透水料置換，並根據本工程特點在下游壩腳加設了反濾層.為提高壩基的整體性和防滲性能，對趾板進行了固結和帷幕灌漿.達到了安全、經濟、便於施工的目的，運行情況良好，可為面板堆石壩的設計和研究提供參考與借鑒In order to optimize the parameters of running top coal under different coal and gangue fragmental size, on the basis of measuring and analyzing the distribution character of top - coal fragmental size, running top coal was studied for the coal seam with dead - unconsolidated thin sandstone roof by loose medium model experiment
