问题的提出——本文讨论的内容。随着我国的顶管施工技术不断发展,采用顶管法施工,在各城市日渐广泛。考虑顶管施工方案时,计算顶力值是一个重要数据;计算成果精确与否,有时会影响工程的成败。笔者在工作实践中,发现计算顶力方法上,存在一些问题。目前计算顶力是根据《市政工程施工技术规程》(以下简称《规
Raise the question - the content of this article. With the continuous development of jacking construction technology in our country, the pipe jacking construction has been widely used in various cities. Taking into account the pipe jacking construction program, calculating the top force value is an important data; whether the calculation result is accurate or not will sometimes affect the project’s success or failure. In my work practice, I found that there are some problems in the calculation of the top force method. The current top-calculation is based on “Municipal Engineering Construction Technical Regulations” (hereinafter referred to as "rules
