span of arch
Examples
- Through analyzing all kinds of construction methods of building metro station under shield driven method in many countries , this paper studies the construction technique ( method ) of building metro station under shield driven method , taking in guangzhou no . 3 metro line , and linhe xilu station as the actual object . according to station class , function and topography and geology , the station schemes of twin - bore tunnel ( island ) , firstly , three parallel tunnels ( island ) , tri - bore tunnel ( island or side ) and four parallel tunnels ( island or side ) are proposed . secondly , the shape and main parameters of station structure on two schemes are analyzed with load - structure mode , for different overburden depth of tunnel and lining thickness , etc . thirdly , the construction process is simulated in 2d fem . ,
根据建站的规模、使用功能及站位地形地质条件，提出了两连拱结构岛式站台车站、三条平行隧道岛式站台车站、三连拱结构岛式和侧式站台车站以及四条平行隧道岛式和侧式站台车站方案；采用荷载?结构模式，对四种方案的主体结构的形式和重要参数进行分析研究，分不同的埋深、衬砌结构厚度和拱形结构的拱跨比进行了多组数值计算；采用平面有限元方法对四种车站结构的开挖施作过程进行了模拟分析。 - In consideration of the soil arch effect between anti - slide piles , a calculation formula for the anti - slide pile spacing was developed , taking the following factors as the controlling conditions - the static equilibrium equation of the frictional resistance and adhesive force between the side of piles and slope soil , which sustains the thrusting force of the landside , and the strength conditions at the medial cross - section and two end sections of soil arch
摘要考虑抗滑桩桩间土拱效应，以桩侧与边坡土体间的摩阻力及黏着力承担滑坡推力的静力平衡条件和土拱跨中与拱脚处截面的强度条件共同控制，建立了抗桩间距的计算公式。
