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 author comes to some conclusions as follow: The Khanate of Kipchak kept the submissive relation to the house of the grand khan and supported the supreme khan of Mongol Empire in the inner politics and the policy to the outside, which gave certain supports to the early communication in the Mongol Yuan dynasty; The Khanate of Kipchak should account for the stop of the communication caused by the foundation of the Khanate of Ogotai which had been supported by the Khanate of Kipchak during the period of the reign from Berke to Mangu Timur; The short-time stop of the communication was also Mongolian central government"s tragedy. The relationships of the Khanate of Kipchak to Yuan dynasty began to become normal during the course of the reign of Tuda Mangu ,Tula-buqa and Toqatai khan, in which the Khanate of Kipchak gave certain devotions to "peace" of the Mongol Khanates. Their relations had been best after the separation of Mongol Empire during the time of ozbeg and Janibeg"s reign which was. the rush hour of our economic and cultural intercourses with the Khanate of Kipchak and other west countries. The development of the relationships to Egypt accelerated the intercourses between this two countries, which indirectly widened the ways of the Sino-Arab communication in the economy and cultures. The relations to Ire Khanate had been very bad for a long time. This stopped the convergence of the Steppe Silk Roads and the Oasis Silk Roads. In other side, this helped the intercourses between Ire Khanate and Christian Europe.

本文认为，蒙古帝国时期，无论在内政还是外交方面，钦察汗国都维护着蒙古大汗的权威，保持着与蒙古大汗廷的臣属关系，这为蒙元早期中西经济文化交流需要的条件做出了一定贡献；别儿哥至忙哥帖木儿统治时期，钦察汗国应对因窝阔台汗国的崛起而导致的中西交通的阻断负一定责任，但这同时也是蒙古中央政府的悲哀；脱脱蒙哥至脱脱统治时期，两国关系开始逐渐恢复，钦察汗国为蒙古诸汗国的&约和&贡献了自己的力量；月即别和札尼别统治时期是两国关系的最密切时期，也是双方经济文化交流和中西交通的高峰期；钦察汗国与埃及关系的发展，一定程度地拓宽了中阿经济文化交流的渠道；钦察汗国与伊利汗国关系恶化和长期的紧张，一方面阻碍了草原丝路与绿洲丝路的交汇，另一方面促进了伊利汗国与欧洲的经济文化交流。
