圬工拱圈增大截面面积加固承载能力验算方法研究

摘要

At-present,plenty-of-masonry-arch-bridges-come-to-the-age-of-reinforcement.The-multi-tudes-of-reinforcement-make-the-study-on-bearing-capacity-checking-method-of-bridge-reinforcement-very-important.Based-on-the-stress-characteristics-of-arch-bridge-reinforced-by-increasing-section-are-a,this-paper-puts-forward-a-bearing-capacity-checking-method-of-masonry-arch-ring-reinforced-by-in-creasing-the-section-area.%目前我国大量圬工拱桥进入加固期，大批的加固任务，使承载力计算方法的研究成为加固领域亟须解决的问题。文中以增大截面面积加固法加固圬工拱圈的受力特点为依据，提出一套承载能力验算方法。
