Using the new numerical model for reinforced joint with consideration of the bond and slip between reinforcing bars and surrounding dam concrete, the 3d fem nonlinear analysis for 292m high xiaowan arch dan under design load working conditions of earthquake was conducted, and the effects of different kinds of reinforcement on stress, slip and transverse joint openings were studied
摘要利用考慮橫縫及跨橫縫鋼筋滑移的拱壩動力非線性模型，對設計地震荷載工況下的小灣拱壩進行了三維動力非線性有限元分析，研究了不同配筋率分佈對跨縫鋼筋的應力、滑移量及其控制橫縫變形的影響。 -
Experimental study on bond - slip characteristics of earthquake - resistant bars for xiaowan arch dam
小灣拱壩抗震鋼筋粘結滑移試驗研究 -
In this paper, with complete calculation micro - mechanics method, mass concrete was taken as three - phase composites, which consists of mortar matrix, aggregate and bond between matrix and aggregate. with nonlinear finite element method, the simulation of static and dynamic mechanics performance of the uniaxial compress concrete specimen of dongjiang arch dam and simple supported beam specimen of xiao wan arch dam was studied by means of the software of msc. marc. the number of all kinds of mortar matrix was calculated according to grading of aggregate of three graded concrete and walraven function
本文採用完全細觀計算力學方法，將大體積混凝土在細觀層次上看成是由粗骨料顆粒、硬化水泥砂漿及其二者之間的粘結界面組成的非均質復合材料，採用非線性有限元方法，在對大型商業有限元軟體? msc . marc二次開發的基礎上，對東江拱壩的三級配混凝土軸壓試件、建設中的小灣拱壩三級配混凝土梁試件在靜、動荷載下的力學性能和破壞過程進行了數值模擬。
