摘　　要：自19世纪初叶至今,国内外桥梁建造高速发展,施工技术水平不断革新和提高,目前,国内外公路、铁路跨越河流进行基础深水施工的桥梁工程极为普遍,但同时具有深水、大流速、裸岩、河床倾斜等条件下进行基础施工的桥梁还不多见。本文以某特大桥为例,介绍了相关地质情况的桩基施工技术。Since the early 19th century,bridge construction has developed rapidly both domestically and internationally,with continuous innovation and improvement in construction technology.Currently,bridge engineering for deep water foundation construction across rivers by highways and railways is extremely common both domestically and internationally.However,bridges with deep water,high flow velocity,bare rock,and inclined riverbed conditions for foundation construction are still rare.This article takes a special bridge as an example to introduce the pile foundation construction technology related to geological conditions.
