Design and Mechanic Analysis for Anchor System on Pylon of Guilin Nanzhou BridgeLi Xiaofeng，Chen Hefeng，Zheng Benhui(Architectural Design and Research Institute of Tongji University,Shanghai 200092,China)Abstract:The pylon of Guilin Nanzhou Bridge is curve,and the steel anchor beam system on pylon is complicated. According to the analysis of theoretical calculation and model experiment,the design of anchor system of pylon is proved safe and reliable,and meets with the criterion at the specified states.Keywords:Nanzhou Bridge；curved pylon cablestayed bridge；anchor system of pylon；mechanic analysis作者簡介：勵(lì)曉峰(1966-)，高級(jí)工程師，工學(xué)碩士。參考文獻(xiàn)［1］公路橋涵鋼結(jié)構(gòu)及木結(jié)構(gòu)設(shè)計(jì)規(guī)范(JTJ 025—86)［S］.
