摘　　要：通过对高温后高强混凝土力学性能的试验研究,探讨了高强混凝土的抗压强度、抗拉强度和抗折强度在不同温度下的变化规律,分析了温度对高强混凝土力学性能的影响机理、爆裂现象、爆裂机理,最后,对进一步的研究进行了展望。Through the experimental study on the mechanical property of high strength concrete （HSC）after high temperature, the influencing law of the compressive strength, splitting strength and rupture strength of HSC under different temperature are discussed. The influence mechanism of temperature to the mechanical property of HSC is analyzed. The explosive spalling of HSC at high temperature and its mechanism are also expounded. Finally, expectation on further research is provided.
