從羅馬到現(xiàn)代混凝土拱壩設(shè)計(jì)
摘要
大壩設(shè)計(jì)可以分為三個主要階段：重力式結(jié)構(gòu)依靠其自重保持穩(wěn)定，拱結(jié)構(gòu)依靠壩肩反應(yīng)力和支撐壩，一個拱壩的設(shè)計(jì)依賴于壩肩反作用力以抵御水壓力當(dāng)然這需要先進(jìn)帶的工程技術(shù)。目前的研究表明，拱壩的發(fā)展歷史發(fā)生于五個階段。目前世界上最古老的拱壩是由在法國和西班牙的羅馬人修建。其次是蒙古人在13世紀(jì)和14世紀(jì)間于伊朗修建的水壩，然而，一直到19世紀(jì)，拱壩的設(shè)計(jì)才取得了重大的進(jìn)展。4座具有卓越成就的拱壩結(jié)構(gòu)，米爾阿勒姆壩（印度1804年），瓊斯瀑布水壩（加拿大1831年），左拉大壩（法國1854年）和帕拉馬塔大壩（澳大利亞1856年）。澳大利亞工程師開創(chuàng)了用混凝土作為筑壩材料的先河（即75 -邁爾斯和利斯哥1號壩）?，F(xiàn)代混凝土拱壩設(shè)計(jì)于20世紀(jì)初引入北美：例如，定角拱，雙曲拱。由于沒有重大的設(shè)計(jì)突破發(fā)生，已發(fā)生的設(shè)計(jì)和現(xiàn)代拱壩是在單半徑，恒定角度或雙曲拱壩設(shè)計(jì)的。但是作者認(rèn)為，增設(shè)混凝土作為建筑材料標(biāo)志著重大的革新，為更靈活的拱壩體型設(shè)計(jì)提供了前提條件。

Historical Development of Arch Dams.
From Roman Arch Dams to Modern Concrete Designs
Abstract
Dam designs may be divided into three main types : gravity structures relying on their weight for stability, arch structures using the abutment reaction forces and buttress dams. The design of an arch dam relies on the abutment reaction forces to resist the water pressure force and it requires advanced engineering expertise. The present study demonstrates that the historical development of arch dams took place in five stages. The world's oldest arch dams were built by the Romans in France and Spain. They were followed by the Mongols who built dams in Iran during the 13th and 14th centuries. However it is not until the 19th century that significant progress in arch dam design was made. Four remarkable structures were the Meer Allum dam (India 1804), the Jones Falls dam (Canada 1831), the Zola dam (France 1854) and Parramatta dam (Australia 1856). Australian engineers pioneered the use of concrete as a construction material for arch dams (i.e. 75-Miles and Lithgow No. 1 dams). Modern concrete arch dam designs were introduced in North-America at the beginning of the 20th century : e.g., constant-angle arch, double-curvature arch. Since no major design breakthrough has taken place and modern arch dams are based upon the single-radius, constant-angle or double-curvature arch design. It is the writers' opinion that the introduction of concrete as construction material marked a major innovation in allowing a flexibility in arch shape design.
