This paper evaluates the underground water resources and its safe levels of miming, and then studies the availability of molepipe drainage, a kind of practical underground water regulation technique. starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well - studied determination method of determining the two hydrographical coefficients : rainfall infiltration replenishment rate and irrigation replenishment rate. then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage, exploitation on water regulation
論文從灌區的地下水資源及其可開采量評價分析方面入手，在對兩個主要的水文地質參數即降雨入滲補給系數、灌溉入滲補給系數確定方法研究的基礎上，對灌區的地下水資源狀況進行分析，依據灌區的灌溉、降雨、排水條件及各種現狀因素，建立了地下水資源量計算的數學模型，西安理工大學工程碩士專業學位論文計算得到青銅峽灌區地下水的最大補給量和可開采量;另外對在開發利用地下水資源過程中的地下水位的調控進行了初步的探討，在銀北灌區開展對暗管排水調控地下水位的試驗研究。 -
Combined with hydrogeological information gained by exploration and hydrographical drilling, groundwater types and leakage ways under the water curtain corridor and air - cushioned surge chamber are found out, which provide the grouting engineering with more effective treatment
結合水電工程勘查及水文地質鉆探獲取得的地下水文地質信息，查明了水電站水幕廊道和氣墊調壓室滲水的地下水類型和滲漏途徑，為調壓室的進一步灌漿處理提供了依據。 -
The geological factors are important besides them, which are related to the loess landslide and evolution of gullies, specially for bedrock folds, bedrock joints and loess joints. in field, the data of the bedrock elevation in the three sheets combined with the research from south to north lively were got by gps12xlc pocket locator, the type and its evolution of bedrock, loess landslides and distribution of hydrographical net were explored too. at office, the synthetic analysis and contrast were used including the simulating analysis about the data by mapinfo 6. 5, software of gis, discussion and communication with experts, in order to demonstrate and reveal the rules between the loess landforms and its pale bedrock landforms and the impact of structure on erosion interiorly in shaan bei
在野外，以代表調查區和路線調查相結合的方法，利用gps12xc型手提式定位儀採集基底高程數據，實地觀察基底地層產態變化規律和特徵，觀察黃土地貌、黃土崩塌、水系展布及土壤侵蝕等與地質構造之間的關系；在室內主要進行綜合分析與對比，利用gis系統的mapinfo6 . 5軟體對採集數據模擬分析，並將認識成果與其他專家學者進行交流和探討，從而論證和揭示陜北黃土地貌南北縱向分異與基底古樣式關系特徵及水土流失與構造因素之間的內在規律。
