In this paper, the 3-D finite element relocating mesh method is used to calculate the temperature field and the thermal creep stress field of spillway dam and mid level outlet dam in certain roller compacted concrete gravity dam, sensitivity analysis have been down with different parameters, such as placing temperature, the location of cooling pipe, cooling temperature, time for water supply, ascended-layer of concrete, intermissive time and different placing time, and the commendatory construction scheme have been put forward in such analysis; according by the test result on the two scheme of concrete aggregate combination (basalt as coarse aggregate and limestone as fine aggregate, basalt as coarse aggregate and basalt as fine aggregate), simulation analysis on temperature field and thermal creep stress field of the commendatory construction scheme have been down, and analysis have also been down on temperature field and thermal stress field of the two different aggregate combination, the result indicates that the spillway dam and mid level outlet dam which adopted these two aggregate combination can both satisfy the require of design crack resistance in concrete, furthermore limestone as fine is better than basalt as fine aggregate; the effect of summer water storage and winter water storage on the temperature field and thermal stress field have been analyzed, comparing with winter water storage, in summer water storage scheme the maximum tensile stress at abnormal concrete in upstream fill is decreased by 0.1~0.3MPa and there are no evidence change of the maximum tensile stress at other parts, which indicate that summer water storage is avail for the crack resistance of upstream fill; according to the simulation calculating result and comparing temperature simulation calculating results and temperature controlling measures of some similarity projects both completed and construction, synthesis appraise have been carried to the design temperature controlling measures of dam, and the temperature controlling measures of this project have been brought forward, all these have great reference value on the design of temperature controlling measures and the optimization of the construction scheme.
本文采用三维有限元浮动网格法仿真计算程序,对某碾压混凝土重力坝的溢流坝段和中孔坝段分别进行了三维有限元温度场和温度徐变应力仿真计算分析,对浇筑温度、冷却水管的布置方式、冷却水温、通水时间、浇筑升程和间歇时间、不同开始浇筑日期等参数进行了敏感性分析,在此基础上提出了推荐的施工方案;根据两种骨料方案(玄武岩粗骨料+灰岩细骨料方案;玄武岩粗骨料+玄武岩细骨料方案)的混凝土性能试验研究成果,对推荐的施工方案进行了温度场和温度徐变应力仿真计算,并对比分析了两种不同骨料情况下的温度场和温度应力,结果表明溢流坝段及中孔坝段采用上述两种骨料均能满足混凝土的抗裂设计要求,且灰岩细骨料优于玄武岩细骨料;计算分析了夏季蓄水和冬季蓄水对坝体温度场和温度应力的影响,夏季蓄水方案与冬季蓄水方案相比,坝体上游变态混凝土区域最大拉应力小0.1~0.3MPa,其他部位最大拉应力无明显变化,夏季蓄水对坝体上游面混凝土的抗裂有利;根据仿真计算成果并通过比较国内一些已建和在建的类似工程的温度仿真计算成果及采取的温控措施,对大坝的设计温控措施进行了综合评价,并提出了该工程的温控措施,对温控设计和优化施工方案具有重要参考价值。

The main results are as follow: strong patent scope is helpful for information disclosure. However, the effect of patent scope on social welfare and pace of technological progress shows a quasi inverted-U shape. Therefore, the optimal patent scope is finite.
我们发现:强的专利保护宽度有利於资讯披露,但其对社会褔利和技术进步的影响却呈近似的倒U型,故在不同的情况下都存在一个专利保护宽度的最优取值区间。

The study indicates that:install MOA at line side is the most effectiveness method to protect banked switch,keep up the tower dielectric level will increase the probability of lightning stroke, but it can reduce the amplitude of lightning intrusive waves, this is advantage to the protection of the substation ,and lightning protective effect of this mode is the best.
研究表明:在开关前安装MOA是保护热备用开关的最有效措施,即使在最严重的情况下,热备用开关的绝缘裕度也超过10%,可以保护开关的正常使用;不增加进线保护段杆塔的绝缘水平会增加进线保护段的雷击概率,但是此措施可以降低入侵波的幅值,对变电所防雷有利,这种防护方式的防雷效果最好。
