| 摘 要： | 温度裂缝严重危害大体积混凝土的结构安全.目前,对混凝土温度应力及裂缝的研究不断深入.两个工程实例的研究表明,因温度及干缩而产生的拉应力破坏可能发生在混凝土早龄期.因此,为防止大体积混凝土温度裂缝产生,对温度和干缩应力与混凝土强度的验算应从混凝土产生温度应力的起点开始,贯穿其应力发展的全过程.

| Abstract: | Thermal crack is harmful to concrete structure. Research of the temperature stress and crack has got great progress. With two instances the failure maybe take place during the concrete early age is indicated. So concrete temperature stress, shrink stress and tensile strength should be monitored as soon as thermal stress coming into being and through out the whole process of tensile strength's development. |

| Keywords: | early age mass concrete temperature stress crack shrink |
