 The Niukouyu reservoir, 57 Km to the southwest of Beijing, was built on the karstified Ordovieian limestone. The strong karstification along the regional faults makes the reservoir serious leakage that has caused the groundwater polluted. According to the study on the hydrogeological conditions and the leakage of the reservoir, the conclusions have been drawn as follows: 1.The characteristics of limestone block bearing water in the Niukouyu reservoir area is basically controlled by the evolution process of Niukouyu... The Niukouyu reservoir, 57 Km to the southwest of Beijing, was built on the karstified Ordovieian limestone. The strong karstification along the regional faults makes the reservoir serious leakage that has caused the groundwater polluted. According to the study on the hydrogeological conditions and the leakage of the reservoir, the conclusions have been drawn as follows: 1.The characteristics of limestone block bearing water in the Niukouyu reservoir area is basically controlled by the evolution process of Niukouyu polje. The zone 510 m below the groundsurface is karstified strongly. The red clay filling in the karstic fissures has decreased the transmission and the storage capacity of the waterbearing block of limestone. The zone 10 m below the surface principally is the fissured block bearingwater. The fissures and small conduits in limestone are well developed along the fault F2. 2.There are the phreatic flow which shallow cycles and fissured diffusion flow deeply cycling, both are effected more or less by the reservoir water existed in the waterbearing block of limestone. 3.Boreholes N14 and N11 separctely belong to two different hydrogcological units, the possibility of leaking from N14 to N11 is very small. 4.Reservoir water leakes dowm to the waterbearing block of limestone through the fissures where the limestone system has been destroyed. The main leakage zones are reservoirN14N10Mabao spring, reservoirN7Mabao spring and under the base of the complementary dam No.4. The leakage through the deep limestone aquifer under the main dam is not very serious.  位于北京西南57km的牛口峪水库建于奥陶系喀斯特化石灰岩之上。沿着区域性断层强烈的喀斯特作用使得水库发生严重渗漏,并污染了地下水体。根据水文地质条件和对水库渗漏的研究,可得出如下结论:1.牛口峪水库地区石灰岩含水体的特征主要受到牛口峪坡立谷演化过程的控制。地表下5—10m是喀斯特强烈发育带,但是充填在喀斯特裂隙中的红粘土降低了石灰岩含水体的导水性和储水能力。深于地表以下10m处,主要为裂隙含水体。石灰岩中的溶蚀裂隙和小管道沿着F_2断层发育。2.石灰岩含水体中存在着受库水影响较大的浅循环潜水流和深循环裂隙扩散流。3.牛14孔和牛11孔分属于两个水文地质单元,库水向牛11孔方向渗漏的可能性很小。4.库水主要通过表层灰岩体结构遭受破坏的石灰岩裂隙进行渗漏。最主要的渗漏带是牛14孔—牛10孔—马刨泉带,其次是水库—牛7孔—马刨泉带和四副坝坝基渗漏。主坝坝基深层石灰岩体中的渗漏是存在的,但不严重。  A coupled model of finite element method with linear programming was used for the management of karstfracture water resource in Linzi District of Zibo Municipality, Shandong Province.

A coupled model of finite element method with linear programming was used for the management of karstfracture water resource in Linzi District of Zibo Municipality, Shandong Province. The mathematical model is given by where H is the groundwater head, Tx and Ty are the components of transmissivity tensor. W is the replenishment in the vertical direction. ST is the storativity, Qij is the pumping rate in well j at time level i. D is the flow domain. T1 is the first kind of boundary, T21 is the impermeable boundary, T22 is the described flux boundary. H0 and f are the described heads and q is the described flux. The model can be decomposed into 2 models and approached by finite element method.The optimal management model is as follows :Objective function:Subject towhere Q(j,1) is the pumping rate in well j at time step l. a (i. j. kl+ 1) is the influence coefficient,s (i. k) is the constraint of drawdown in well i at time step k and s1 (i, k) is the additional drawdown. a(i. j, k l + 1) and s1 (i, k) can be computed by finite element method. The optimization model has been solved by simplex method. The results are shown in this article.  将有限元法和线性规划相结合，建立临淄地区的喀斯特—裂隙地下水管理模型，如何根据短时期的优化管理结果进行长时期地下水资源管理和地下水水头预报，如何确定水力约束条件，对严重超采山丘区喀斯特—裂隙水，当开采量缩减到优化开采量时产生的水文地质现象进行了理论解释。  The powerhouse foundation of Yinzidu Hydropower Station is located on the fault F14.The degree of construction difficulty would be added due to the unfavorable geological conditions of the foundation rockbody such as karst,fissure and cracked zones as well as stratum with mud.Elaborately designing and selecting reasonable blasting parameters as well as adopted deepholepresplit blasting method in excavation not only make the net reliably detonate,but also there are not big stones flying over large distance,there... The powerhouse foundation of Yinzidu Hydropower Station is located on the fault F14.The degree of construction difficulty would be added due to the unfavorable geological conditions of the foundation rockbody such as karst,fissure and cracked zones as well as stratum with mud.Elaborately designing and selecting reasonable blasting parameters as well as adopted deepholepresplit blasting method in excavation not only make the net reliably detonate,but also there are not big stones flying over large distance,there are not big blasting dumps and pits,the dimension of stone is even and the presplit planes are relatively smooth,ratio of half hole is up to 90%.This is favorable for quickly excavating and supporting the sides of powerhouse.  引子渡水电站厂房基础坐落在F11断层上,地基岩体的喀斯特、裂隙破碎带及夹泥层等不良地质因素增加了施工难度,但由于采用深孔预裂爆破的方法进行施工开挖,并精心设计及选择合理的爆破参数,使网络可靠的起爆,因此爆破时无大的远距离飞石产生、无大的爆堆爆坑现象、预裂面较为平整、岩石块度均匀、半孔率达90%,整体效果较好,为加速厂房边坡的开挖和支护创造了有利条件。
