| 摘 要： | 郑开城市通道顶推箱涵上部覆土较薄，而箱涵的跨径、顶进长度为目前国内之最。为了保证箱涵顶进时路面不会出现随箱涵移动、断裂以及塌陷等现象，可采用大管棚支护技术进行顶进箱涵的顶部防护。

| Abstract: | The soil covering on incremental launching box culvert in the city channel from Zhengzhou to Kaifeng is thin, while the span and the jacking length of the box culvert is the largest in China. To avoid moving with the box culvert, rupture, collapse and some other phenomena appearing to the pavement in the process of jacking box covert, the large pipe shed support technology can be adopted to protect the top when jacking box culvert. |
