【摘要】：東湖水庫是南水北調東線一期工程膠東輸水干線工程的重要調蓄水庫。水庫位于濟南市東北部歷城區(qū)郭店鎮(zhèn)老僧口村東北部白云湖與小清河之間,工程永久占地8073.56畝,東湖水庫年供水量8097萬m3。庫區(qū)內原有農(nóng)業(yè)灌溉水井200多眼,深度20～30m不等,部分穿透相對不透水層,為確保水庫蓄水安全和減少滲漏,對井筒及外側反濾體進行回填封堵是必要的。本項目依托南水北調東線一期工程濟南～引黃濟青段東湖水庫工程庫內水井封堵的現(xiàn)場試驗,論證庫內水井封堵的必要性和應采取的加固技術措施。主要內容如下： 灌漿加固技術的優(yōu)選研究、適合該水庫數(shù)值分析的物理模型及數(shù)學模型的建立、加固效果的分析方法。 (1)庫內水井封堵的現(xiàn)場試驗,選擇東湖水庫庫內水井典型封堵實例,采用高噴灌漿方案對庫內水井進行封堵,對比封堵前后水井的滲漏量,對其可行性進行理論研究。 (2)庫內水井封堵的必要性研究,采用地質鉆探與現(xiàn)場壓水試驗相結合的方法,探明水井周圍的地質特征,根據(jù)現(xiàn)場試驗成果和理論分析數(shù)據(jù),分析庫內水井封堵的必要性。 (3)庫內水井封堵的數(shù)值模擬,根據(jù)現(xiàn)場試驗的物理模型,建立適合該水庫庫內水井數(shù)值模擬的數(shù)學模型,利用有限元法計算不同口徑水井在封堵前后的滲漏量,對后期灌漿封堵庫內水井提供技術支持。 (4)加固技術及加固效果的分析方法,根據(jù)庫內典型水井的現(xiàn)場壓水試驗和數(shù)值分析成果,確定合理的加固技術和效果分析方法。
[Abstract]:Donghu Reservoir is an important reservoir in Jiaodong Water main Line Project of the East Route of South-to-North Water transfer Project. The reservoir is located between Baiyun Lake and Xiaoqing River in the northeast of Guodian Town, Laoshengkou Village, northeast of Jinan City. The project covers a permanent area of 8073.56 mu, and the annual water supply of Donghu Reservoir is 80.97 million m3. The original agricultural irrigation wells in the reservoir area have more than 200 eyes, with depths ranging from 20m to 30m, and some of them penetrate the relatively impermeable layer. To ensure the safety of reservoir storage and reduce leakage. It is necessary to carry out backfilling and plugging of wellbore and lateral filter. This project relies on the field test of water well plugging in the reservoir of Donghu Reservoir of Jinan ~ Yellow River diversion from Yellow River to Qingqing section of Donghu Reservoir in the first phase of South-to-North Water transfer Project. The necessity of plugging wells in the reservoir and the technical measures to be taken to strengthen them are demonstrated. The main contents are as follows: The optimum selection of grouting reinforcement technology is suitable for the establishment of physical and mathematical models for numerical analysis of the reservoir and the analysis method of reinforcement effect. 1) the field test of the water well plugging in the reservoir, the typical example of the water well plugging in the reservoir of Donghu Reservoir is selected, the high jet grouting scheme is adopted to seal the inside well in the reservoir, and the leakage rate of the well before and after the plugging is contrasted. The feasibility of the theory is studied. 2) the necessity of plugging wells in the reservoir is studied. The geological characteristics around the wells are proved by the method of combining geological drilling with in-situ water pressure tests, and the data are analyzed according to the results of field tests and theoretical analysis. The necessity of water well plugging in storehouse is analyzed. According to the physical model of the field test, the mathematical model suitable for the numerical simulation of the reservoir water well is established. The finite element method is used to calculate the leakage of wells with different caliber before and after plugging, which provides technical support for filling and plugging the inner wells of the reservoir in the later stage. 4) strengthening technology and analysis method of reinforcement effect, according to the field water pressure test and numerical analysis results of typical wells in the reservoir, the reasonable reinforcement technology and effect analysis method are determined.
