通过综合国外顶推合龙工艺和国内温度配切合龙工艺有点，提出了全新的顶推辅助合龙工艺，并介绍了顶推辅助合龙工艺实施条件、关键施工参数和主要工艺措施的计算分析要点以及实施情况。
By abstracting the advantage of the pullback method abroad and the deomestric temperature-cutting method, a new assistant pullback method is put forward and brought into practice actually. In this paper, the analysis key point of practice conditions, key parameter of practice, main measures of the method and the performance are introduced.
