An accident practice of excavation pit on soft soil ground 软土地基某基坑工程事故分析及处理
Application of neural network to forecasting deformation of bracing of deep excavation pit 深基坑变形的神经网络预测
Ensure that the side of the excavation pit is properly shored before you go down to do work 进入坑洞里工作前,先确定坑洞的墙壁是否有支柱牢固地支撑着。
He reportedly said that he only planned to have a photo of himself taken standing near the museum ' s excavation pit 他说他从小就被这些陶俑迷住,见到他们的时候就完全疯掉了。
It is difficult to use pre - stress anchor technique to the deep excavation pit on the coast , in which the stra - tum is highly filled with water and subjected to the penetration of sea water , therefore there is no suc - cessful experience 濒临海边的深基坑,地层含水量高,渗透性大,易受海水渗透影响,在这类基坑中应用预应力锚杆技术困难极大,鲜有成功的工程经验。
In addition , based on the “ foundation pit failure science ” , the four foundation pits accidents and the reason of them have also been investigated , and the security forewarning system of the excavation pits has been introduced in order to nip failure in the bud 在引进了“基坑工程失败学”基础上,分析了4个基坑事故形式及其产生的原因,提出构建基坑开挖工程的安全预警系统,防患于未然。
But now , succeasful application for the pre - stress anchor technique in the same case has been gained by use of one construction method of orifice ponding pouring in the deep excavation pit supporting in xiamen postal edifice , which can be taken for example on similar engineerings 在厦门邮电大厦探基坑支护的预应力锚杆工程中,采用一种“孔口堵水注浆”的施工方法,取得成功,可为类似工程提供借鉴。
Deformation control of deep excavation pits is firstly introduced in detail , and new conceptions of effective coefficient , effective area , no - effective area and critical line , including the referential criteria and economic - effective measures of deformation control , have been put forward 摘要文中首先对深基坑工程变形控制进行了详细的论述,提出了基坑有效系数、有效区、失效区、临界线的新概念,同时提出了变形控制参考标准和经济有效的变形控制对策。
