| 中文摘要: |
| 本文以江苏宿淮高速公路京杭运河特大桥主墩施工为背帚，对高强度大体积泵送混凝土施工技术方案进行了研究．并对监控结果进行了分析。实践证明，采取降低混凝土绝热温升、“内散外保”以及“双掺”技术和测温监控相结合的技术方案是经济可行的。 |
| 英文摘要: |
| Based on constructing piers of super bridge in the Grand canal in Jiangsu province,it studied temperaturecontrolling methods used in high quality and large volume pumped concrete construction and analyzed the result of inspection test.lt is approved ecomomical and feasible and could decrease the quantity of heat,dispersing inside and preserving outside, mixing into fly-ash and additives, measuring and controlling temperature. |
