宜万铁路齐岳山隧道地质水平钻探应用技术

Study on Application Technology of Geology Horizontal Drilling in Qiyueshan Tunnel at Yiwan Railway

摘要:

前地质探测是隧道安全施工的重要保障，水平钻探技术具有直接和准确的特点，因此快速水平钻探技术成为超前地质探测的主要手段之一。以宜万铁路齐岳山隧道为背景，研究了隧道施工过程中快速水平钻探的点位选择、钻进工艺、数据处理等技术，探讨了快速水平钻探与其他探测手段的配合方法。

Abstract:

Advance geology exploration is an important safeguard of tunnel excavation. Horizontal drilling technology has the character of directness and exactness. For this reason, Fast Horizontal drilling technology is considered as one of the important geology exploration method. Some important factors , such as drilling position selection, drilling techniques and date treating techniques are studied, taking Qiyueshan tunnel of Yiwan railway as an example. The cooperating method of fast Horizontal drilling technology with other exploration methods is also studied.
