地震时未达龄期混凝土的处置
|
摘要
地震前已浇筑的未达龄期混凝土的处置是地震后在建工程项目复工的必要条件。在处置该问题时,需要解决在什么情况下应开展混凝土质量是否受到地震影响的评价工作,需要解决如何评价混凝土强度及钢筋锚固能力是否受到地震影响。目前,内地缺少对该问题的研究。结合四川地区地震后的实际工作,介绍了内地相关的研究情况,对台湾地区的研究情况及所采取的对策进行了简要介绍,并对成都地区开展该项工作的基本情况作了总结。
Treatment of early age concrete poured before earthquake is necessary condition for continuing construction in process after earthquake.It includes that when to develop the evaluation of whether the concrete quality being influenced by earthquake,and how to evaluate that whether the concrete strength and the anchorage ability of steel bars are influenced by earthquake.Combining with the actual work in Sichuan area after earthquake,the corresponding research situation of mainland is introduced,as well as the countermeasures adopted in Taiwan.Moreover,the basis situation in Chengdu is concluded.
