The paper discussed the construction technology and attentions of retailing backwall refill for flowing cement flyash. 阐述了流态水泥粉煤灰作为一种新型台背回填材料的工艺施工技术要点及施工中的注意事项。
Through an example comparing the new method with Rankine theory, it was shown that the new one can calculate the earth pressure at the un-passive state and considers the effect of the local force on the earth pressure distribution on the backwall. 通过算例与朗肯理论的比较结果表明,提出的方法可用于计算土体的非极限被动土压力,且该方法考虑了顶管反力这一局部荷载对墙后土压力分布的影响。

In this paper the authors approach the application of drilling mud to face pre-injection, backwall infilling injcetion, roof fall space infilling injection and split zone infilling injcetion. 本文探讨了泥浆在工作面预注浆、壁后充填注浆、冒空区充填注浆和离层带充填注浆中的应用。
Under the counterforce on the rectangular open caisson working well during pipe jacking, the backwall displacement curve was assumed to be parabolic and the relation between the displacement and earth pressure was used to calculate the earth counterforce. 根据顶管工程中矩形沉井工作井后背墙变形情况,假定后背墙在顶管反力作用下变形为抛物线形,提出采用与位移有关的土压力来计算土体反力。
