文物古塔下高速铁路浅埋隧道修建技术探究

Exploration on express-railway shallow-buried tunnel construction technology under the ancient cultural relics tower

如何正确处理高速铁路浅埋隧道修建和文物古塔保护之间的矛盾一直是个技术难题。依托浅埋下穿明朝古塔——厦河塔的金温铁路厦河塔隧道工程,采用静态爆破+机械开挖方式、静态爆破+控制爆破方式结合组织施工,采取减振处理、塔体防护等一系列措施,有效保证了该工程的安全快速施工。

It is always a technical difficulty of how to correctly deal with the contradiction between express-railway shallow-buried tunnel construction and ancient cultrual relics tower. Based on Jinwen railway Xiahe tower tunnel engineering of shallow-burried underpassing ancient tower-Xiahe tower in Ming dynasty,the paper adopts the organization construction by combining static blasting ＋ mechanical excavation method with static blasting ＋ controlling blasting method,applies a series of measures including vibration reduction processing and tower body protection,and effectively guarantees the safe and fast construction of the engineering.
