摘　　要：以某高层基础承台施工为例,研究了大体积混凝土裂缝控制的方法,介绍了裂缝控制的技术措施。采用电子测温仪对承台大体积混凝土水化热进行了监控,根据监测结果,就环境温度和养护情况对混凝土温度的影响进行了分析,结果表明环境温度的骤变对裂缝的控制影响很大。该工程所采用的技术措施成功地控制了裂缝的产生,对同类工程有一定的借鉴意义。It uses the cushion cap of one high-rise building as an example, studies the crack control methods of mass concrete, and introduces the technological measures of crack-control. The hydration-heat of concrete is measured with electronic monitoring control system, and the measured results are researched. Furthermore, the influence of air temperature and curing methods on the temperature of concrete is carried out. Research results showed that the sharp change of air temperature has a great influence on crack-control. The technological measures adopted in the project are very successful.
