| 3. | Analysis on the cracks of multi - story buildings ' floor slabs and the crack - control measures for the cast - in - place slabs 多层住宅楼板裂缝分析及现浇板防裂措施 |
| 4. | 3 . the causes of the concrete cracking the measures for temperature control and crack repairs are expatiated 阐述了混凝土结构裂缝的成因机理、温控防裂措施、裂缝补救方法。 |
| 5. | It expounds harmfulness and cause of crack of concrete of arch dams , and measures of crack prevention in such structures are suggested 论述了拱坝混凝土产生裂缝的危害性及其原因,并针对性地提出多种温控防裂措施。 |
| 6. | The study of the mechanism of crack generating and proceeding and the crack control method is a very important subject in the design of construction and the practical construction scheme 研究裂缝的产生与发展机理和温控防裂措施是大体积混凝土结构设计与施工中十分重要的课题。 |
| 7. | The phenomenon of crack that appears in the hydraulic culvert and sluice is explained separately . the rule is concluded . the mechanism that forms the crack is studied 对水工涵闸工程墩墙和底板混凝土的裂缝现象分别进行了阐述,总结其规律,分析其成因,并研究其开裂机理,为采取相应的工程防裂措施提供理论依据。 |
| 8. | The paper presents a series of anti - cracking measures taken during the construction of mass concrete in hot weathers to prevent concrete cracking . with these measures , anticipated results were achieved 摘要文章阐述了热天大体积混凝土施工过程中,到了预期的效果。为防止混凝土裂缝的产生,采取了一系列相应的防裂措施,达了预期的效果。 |
| 9. | The effect of cold wave , layer thickness of construct and sluice to temperature field and stress field are studied . this paper analysis the effect of the first stage cooling and the second stage cooling . pertinent measures of temperature control and crack prevention are suggested , settling the practice problems in projects 重点研究了寒潮、浇筑层厚和蓄水等对拱坝混凝土温度场和应力场的影响;对坝体一期冷却和二期冷却的冷却效果进行了详细分析;并针对性地提出了相应的温控防裂措施,以解决工程实际问题。 |
| 10. | Therefore , the simulation calculation and comparison on the temperature field and the stress field of temperature creeping for many temperature control schemes are made with the application of the 3 - d finite element simulative analysis software , and then a set of effective measures for comprehensive temperature control is optimized and two temperature control schemes are put forward for the application to the project ; with which the problem of temperature and crack control of the anchorage block during the construction of sangequan siphon project is solved satisfactorily 为此,应用三维有限元温度场和温度徐变应力场仿真分析软件进行了多方案的仿真计算和比较,优选了一套行之有效的综合温控防裂措施,提出了两个温控方案并应用于该工程,比较好地解决了三个泉倒虹吸进口镇墩结构的温控防裂问题。 |
