在指出传统的自然轨温放散方法的不足之后，介绍了零应力综合放散法的原理及该法中所考虑的几个主要问题。该法具有锁温准确、不重复放散、扩大施工范围和不受时间限制等优点，可获得较好的经济效益。 After pointing out the shortcomings of the traditional method of natural rail temperature emanation, the principle of zero-stress integrated emanation method and several main problems considered in this method are introduced. The method has the advantages of accurate temperature lock, non-repeated discharge, to expand the scope of construction and not subject to time constraints, access to better economic benefits.
