拱坝应力分析
stress analysis of arch dam
gongba yingli fenxi拱坝应力分析(stress analysis of arehdam)研究拱坝坝体和地基在各种荷载作用下的应力和变形的方法。在拱坝设计中,拱坝体形和厚度的选择,混凝土标号及地基软弱部位的加固等,均须参照应力分析的结果来确定。拱坝的应力分析,包括数学分析、结构模型试验和原型观测。原型观测是在已建成的坝上进行观测,了解其工作安全状况,校验设计结果,并为以后的科学研究提供资料。 拱坝由于结构复杂,小型工程可采用拱冠梁法。对于大型工程,过去多采用拱梁试(分)载法和结构模型试验。薄拱坝有采用有限差分法的。20世纪70年代起,逐渐采用有限单元法。 为了统一标准,在规定最大设计应力的同时,须规定应力分析方法。因拱坝的应力分布和最大拉、压应力,常随分析方法而改变。考虑各国已建成的大型拱坝都有拱梁试(分)载法的计算结果,拱坝应力分析如采用拱梁试(分)载法,可与已建拱坝进行对比,便于作出安全的评价。 拱梁试(分)载法将空间壳体化为杆系来计算,力学概念明晰,在计算过程中,能逐渐了解其力学机理,便于修改体形和调整厚度,但只能算出坝体应力。在分析地震反应、孔口影响及地基不均匀性等方面,不如有限单元法好。目前,国内外均有拱梁试(分)载法和有限单元法的通用程序。一些大型拱坝设计,常同时采用这两种方法,有时还辅以结构模型试验。
