To give the definition of the mass concrete and to concrete\'s cracks together with practical meanings of control ,and give a brief review on the research in the field at home and abroad, at last, methods to control temperature crack of the mass concrete from several aspects such as design measures,concrets material, construction schedules.etc are summed up; To explain the physical mechanics of the concrete and computing methods-Difference Method and Finite Element Method, and illustrate the application of their specific methods repectively;Several temperature factors that can influence the temperature stress of mass concrete baseplate are analyzed. The influence degree of temperature factor can be got through the ANSYS simulation computation the control of temperature can control the temperature stress, consequently control the temperature crack of mass concert baseplate; through the influence of the crack resistance ability of mass concrete baseplate which takes the reinforcement as a part is analyzed. By ANSYS simulation, the best suited volume ratio of reinforcement is found out, at same time the layout of reinforcement with the same volume ratio can also affect the resistance ability of mass concrete baseplate. Sum up of above analysis, anti-crack function of steel bar in early mass concrete baseplate is obvious, so it\'s necessary to consider beneficial effect of construction steel bar in research of temperature control on mass concrete baseplate.

本文先容了大体积混凝土及混凝土裂缝的基本概念，对国内外在这个领域里的研究现状作了扼要叙述，并从结构设计、混凝土材质、施工措施等方面总结了大体积混凝土温度裂缝控制的方法及防止措施；阐述了混凝土的基本物理力学性能，总结了大体积混凝土温度计算的方法——差分法和有限元法，并分别举例说明其具体应用的方法；分析了影响大体积混凝土底板温度应力的几种温度因素，利用ANSYS模拟计算，得出了每种因素的影响程度，通过分析提出了在这几种温度影响因素下如何通过控制温度以达到控制温度应力从而来控制裂缝的具体建议；针对大体积混凝土基础底板中配筋的不同对混凝土底板抗裂能力的影响不同，利用ANSYS进行模拟分析，得出底板中最合适的体积配筋率，同时分析了在相同体积配筋率下钢筋的具体布置对大体积混凝土基础底板抗裂能力的影响，分析表明，配置钢筋对混凝土结构的开裂阻止作用明显，在研究大体积混凝土温度裂缝题目时，要考虑钢筋在其中的有利作用。

Pointing to several texts of the Bible (Matthew 7:14; 22:14) and to sayings of great spiritual doctors, the rigorists defend as probable the thesis that not only most Christians but also most Catholics are doomed to eternal damnation.

指着几本圣经（马太7时14分； 22时14分），并在熟语的伟大精神医生， rigorists捍卫作为可能的论点，即不仅大多数的基督徒，但也可能是最天主教徒，是注定要永恒

Getting a grade like a B-plus or a C-minus adds or subtracts a few tenths of a point. An F is a failing grade worth zero toward a student's grade point average.

得到一个类似B+或者C-的等级会加上或减去几个0.1分。F是相对学生平均等级分来说未过关的等级，相当0分。

At present this VC, PE heats up China only then at 2006, 2007, two this years nice to the benefit of VC, PE element cashs in succession: Cent buy reform solved equity to exit difficult obstacle; Do poineering work board the anticipation that roll out; Field of A stock market takes a cattle, point to soare; The electric power of cent numerous medium, Baidu, Meng Niu, Shang De stimulation that exits case to earn a few times at every turn is waited a moment.

中国目前这波VC、PE热始于2006、2007年，这两年对VC、PE的利好因素陆续兑现：股权分置改革解决了退出难障碍；创业板推出的预期；A股市场走牛、股指暴涨；分众传媒、百度、蒙牛、尚德电力等退出案例动辄赚几十倍的刺激等等。
