【摘要】：水庫(kù)壩區(qū)滲漏不但可能導(dǎo)致危害性滲透破壞而影響大壩的安全穩(wěn)定性,還會(huì)改變河流的基本特征和下游河道的水文情勢(shì),并且會(huì)對(duì)周邊地下水環(huán)境產(chǎn)生影響。因此,需要提前預(yù)測(cè)并考慮地下水滲流所產(chǎn)生的影響,對(duì)所選壩址方案進(jìn)行驗(yàn)證,使壩址方案更加合理、有效。 油房溝水庫(kù)為一綜合用水的水利工程,工程地點(diǎn)位于儀隴縣北部毗鄰巴中地區(qū)的日興鎮(zhèn)附近,壩址位于油房溝上游河源地帶三叉河匯口下游的友誼橋,正常蓄水位406.00m,設(shè)計(jì)洪水位406.09m,校核洪水位407.64m,死水位395.00m,其開發(fā)任務(wù)是農(nóng)田灌溉、鄉(xiāng)鎮(zhèn)生產(chǎn)生活用水和農(nóng)村人畜飲水。 本論文以丘陵地區(qū)油坊溝水庫(kù)壩址區(qū)選擇作為研究對(duì)象,首先對(duì)其進(jìn)行地質(zhì)環(huán)境調(diào)查,包括地形地貌、地層巖性及地質(zhì)構(gòu)造等；其次研究壩區(qū)地下水類型、含水層富水性、地下水補(bǔ)給排泄條件及化學(xué)特征等水文地質(zhì)條件。在此基礎(chǔ)上,建立地下水系統(tǒng)概念模型,并概化模型邊界,同時(shí)建立地下水系統(tǒng)數(shù)值模型并驗(yàn)證。在建立數(shù)值模型的基礎(chǔ)上利用Visual MODFLOW軟件對(duì)水庫(kù)蓄水后壩址區(qū)地下水流場(chǎng)進(jìn)行預(yù)測(cè)計(jì)算,分析地下水滲流場(chǎng)的變化以及對(duì)周邊地下水環(huán)境的影響。之后,對(duì)模擬計(jì)算出的地下水滲流對(duì)壩址周邊地下水環(huán)境影響進(jìn)行對(duì)比分析,得出不同壩址選擇的環(huán)境影響。最后通過(guò)對(duì)比分析結(jié)果,從地下水環(huán)境影響的角度驗(yàn)證壩址選擇的合理性。
[Abstract]:The leakage of reservoir dam area can not only cause harmful seepage damage and affect the safety and stability of dam, but also change the basic characteristics of the river and the hydrological situation of the downstream river channel, and will also have an impact on the surrounding groundwater environment. Therefore, it is necessary to predict and consider the influence of groundwater seepage in advance and verify the selected dam site scheme to make the dam site scheme more reasonable and effective. Yefanggou Reservoir is a comprehensive water conservancy project, located near Rixing Town in the northern part of Yilong County adjacent to the Bazhong area. The dam site is located at the Friendship Bridge in the lower reaches of the Sancha River Huikou in the headwaters of the upstream Yilianggou River. The normal storage water level is 406.00 m, the design flood water level is 406.09 m, the check flood water level is 407.64 m, the dead water level is 395.00 m.The development task is farmland irrigation, township production and living water and rural people and livestock drinking water. In this paper, the selection of dam site of Youfanggou reservoir in hilly area is taken as the research object. Firstly, geological environment investigation is carried out, including topography, geomorphology, stratigraphic lithology and geological structure, and then the type of groundwater in the dam area is studied, and the aquifer is rich in water. Hydrogeological conditions such as recharge and discharge of groundwater and chemical characteristics. On this basis, the conceptual model of groundwater system is established, and the boundary of the model is generalized. At the same time, the numerical model of groundwater system is established and verified. Based on the numerical model, Visual MODFLOW software is used to predict and calculate the groundwater flow field in the dam area after reservoir impoundment, and the variation of groundwater seepage field and its influence on the surrounding groundwater environment are analyzed. After that, the effects of groundwater seepage on the groundwater environment around the dam site are compared and analyzed, and the environmental effects of different dam site selection are obtained. Finally, the rationality of dam site selection is verified from the point of view of groundwater environmental impact.
