First, industry analysis (a) the basic situation in China is a traditional hog production and

14、consumption country, 2008 46.15 million tons of pork, pig stock 462.64 million head by the end pig slaughter 609.6 million. National pig industrys annual production value at around 650 billion yuan, nearly 50% per cent of annual output value of animal husbandry. Sichuan province in 2008 produced 6.5

15、2 million tons of pork, with 694,000 tons of Chengdu city, live pig sell 10.46 million, first 15 Vice-provincial cities in the country. The whole nation advantage regional planning (2008-2015) there are 437 counties (cities), 55, Sichuan, Chengdu has 7 (including in pengzhou). International pig indu

Especially in the vast rural market growth potential. Third, market for pork and higher product quality requirements.

19、Pollution-free pork safety and health has shown a very good market prospects. Four is the market changing. Currently, cold meat, more and more varieties of meat and pork meat products, which accounted for a large proportion of pork consumption, stores, chain stores, supermarkets and other marketing

20、methods is on the rise, and transport has been extended to more than 2000 km in RADIUS. Chengdu is an important River pig resource market, the citys commercial rate reaches above 60% of live pigs, pork and raw materials primary processing products in the domestic and international reputation is high

37、候温和，矿产资源丰富，尤以铜矿著称。铅山河流域理论电力蕴藏量约14108kWh，初步查明的可开发水电装机有 18.46104kW，可开发电量 6.7108kWh，其水力资源之丰富为信江之冠。 铅山河流域是我省暴雨中心之一，也是我省小流域治理规划的重点流域。伦潭水利枢纽工程项目在 2002 年 7 月已经国务院批准立项。第二章 设计的基本资料及水库工程特性第一节 设计的基本资料一、水文气象伦潭水利枢纽坝址处于铅山河支流杨村水中游。杨村水为信江二级支流，发源于武 夷山脉读书尖。河流自南向北流经篁碧、港口、天柱山、港东、杨村、五都等地，在下 坂与石塘水相汇后称铅山河。杨村水主河长 70km，流域面积

38、 465km2，河道平均坡降 6.6。伦潭水库坝址以上集雨面积 242km2、主河长 41.9km，流域平均宽度 5.77km， 主河道平均比降 11.62。坝址附近无水文测站，选择铅山河流域内铁路坪水文站作为 参证站，由 1959 年至 2000 年共 42 年径流资料，推求坝址多年平均流量为 11.0m3/s， Cv=0.31,Cs=2.5Cv，多年平均径流深 1438.8mm，多年平均径流量 3.48?08m3。铅山河 为雨洪式河流，洪水与暴雨相应，多发生在 49 月份，洪水主要由锋面雨形成，台风雨 也能形成较大洪水。经分析计算，坝址设计洪水成果：校核洪水标准（P=0.1%)，相应 洪峰

39、流量为 2640m3/s，洪量 W1=87.73?06m3、W3=154.17?06m3；设计洪水标准 （P=1%）、相应洪峰流量为 1500m3/s，洪量 W1=52.06?06m3、W3=92.08?06m3。铅 山河属少泥沙河流，坝址多年平均悬移质输沙量 4.55?04t、推移质输沙量 1.82?04t。铅山河流域属亚热带季风气候区，流域内各地多年平均气温 18.1，极端最高气温 40.1，极端最低气温-10.6，多年平均相对湿度 79%。多年平均降水量 1908.9mm， 最大年降水量 2856.7mm（1998 年），最小年降水量 1177.1mm（1971 年），多年平均蒸 发量

40、1550.4mm，多年平均风速 1.9m/s，实测最大风速 20.3m/s。二、工程地质1南昌工程学院毕业设计陶小伟本区处华南褶皱系、赣中南褶隆、饶南拗陷区。区内地势东南高、西北低，下游为 低山丘陵区，中上游属中低山中高山构造剥蚀地貌，不良物理地质现象不甚发育。 区内出露地层主要为燕山早期花岗岩。枢纽及库区处于次一级的陈坊永平八都区域隆 起构造带，未发现孕震断裂分布，不存在产生水库诱发地震的可能性，根据 GB18306-2001中国地震动参数区划图，本区地震动峰值加速度小于 0.05g，地震动反 应谱周期小于 0.35s，区域构造稳定性较好。水库区地层岩性单一，组成库盆、库岸的花岗岩体岩性坚硬

41、，透水性弱，库周分水 岭雄厚，库区产生永久性渗漏的可能性小，库岸稳定性较好。未来库区淤积问题不大。 库区内未发现有工业开采价值的矿产资源及古文化遗址分布，淹没影响较小。不存在浸 没问题。坝区含上、下两个坝址，均属构造剥蚀中低山地貌，位于燕山早期侵入的伦潭岩体 上岩性，为细粒花岗岩，岩性单一，一般弱风化微新岩体为中等较好质量岩体。地质 构造较简单，未发现较大的断裂构造及顺河断层。构造节理主要为北东向和北西向两组， 卸荷裂隙发育不明显。坝区的地下水主要为基岩裂隙潜水。地下水埋深多受大气降水和地形条件及季节变 化等因素所控制。岩体透水性则受地形条件、节理裂隙的密度与贯通，节理裂隙充填状 况及岩体风化

42、程度等多种因素影响，一般遵循自上而下，由大到小的规律。据水质分析 结果，坝区河水和地下水对混凝土具中等溶出型侵蚀性。上、下坝址存在的工程地质问题，主要为渗漏及坝肩稳定问题。由于岩体风化及节 理裂隙的影响，坝址基础开挖以后，建基面以下一般为弱中等透水岩体，需作防渗处 理。上坝址可利用基岩埋深较大，建基面以下透水岩体厚度也较大。下坝址拱坝方案右 坝肩，由于局部分布有缓倾角节理裂隙，其与坝区较发育的北西或北东向两组陡倾角结 构组合，存在与拱肩推力方向夹角很小的不利组合面，有沿该组面产生滑动的可能，对 拱肩稳定不利。就工程地质条件而言，上、下坝址均具备修建 90m 左右大坝的条件。而下坝址的工 程地质

43、条件优于上坝址。据本阶段对三条引水隧洞、一条导流隧洞、一个溢洪道及三个发电厂房和下坝址上、 下游围堰作的地质勘探工作，这些建筑物均处于中低山地貌，围岩为细粒花岗岩，洞室 大部分置于弱风化微新岩体，地下水量不丰，地质构造较简单，洞线进出口及厂房区 未见较大的滑坡、崩塌等不良物理地质现象。各引水隧洞线及厂房均未发现大的工程地质问题。上、下游围堰不存在大的工程地质问题。三、筑坝材料及其物理力学性质（一）水库枢纽工程所需天然建材，石料可就地取材，储量及质量均可满足要求。 砂砾料在坝址区缺乏，需在坝区下游较远处采运，其中砂料质量可满足规范要求，但粗2南昌工程学院毕业设计陶小伟骨料级配较差，粗细骨料储量均

44、可满足需求。 （二）重要物理力学设计指标 （1）坝址处地基物理力学设计指标坝址处具有砂质亚粘土覆盖层，河床处覆盖深度约为 5 米，两岸垂直坡面覆盖左岸 3 米，右岸 12 米。砂质亚粘土覆盖层物理力学指标如下：干容重=1.59/3 饱和容重誗=2.00/3浮容重=0.98/3 渗透系数 K=4.510-6/凝聚力=0.38/2 内摩擦角?20.570（2）筑坝材料 1.砂壤土干容重=1.70/3 饱和容重誗=2.10/3浮容重=1.00/3 渗透系数 K=2.510-5/凝聚力=0.29/2 内摩擦角?300湿容重=1.90/32、粘土防渗体干容重=1.65/3 饱和容重誗=2.07/3 浮容
