外文摘要：A large number of studies have shown that mass concrete structures in the temperature cracks are inevitable。 It is important to adopt reasonable measures to combat and control the crack development。 Thus， mass concrete temperature cracks must be prevented。 Controlling temperature and improving the constraints can start from reducing the thermal stress。 It should be possible to try and improve the ability of concrete cracking and the performance of concrete。 A large number of engineering practices show that the temperature cracks control in massive concrete structures does not depend on any one measure， which must be integrated with practical， full and reasonable consideration。 In conclusion， the large volume of concrete cracks are common quality problems plagued the construction industry for many years。 Thus， the temperature cracks made some targeted control measures with a view to the actual construction which can produce certain significance。
