绵泸高铁大面积采空区采动影响研究及防治措施

依托绵泸高铁内自泸线穿过螺观山脉时遇无法绕避的大面积煤层采空区，比选采动影响对高铁的安全危害最小、地质条件最优的线路方案。通过充分的资料收集、大面积地质调绘对比、再结合钻探、多种物探探测成果进行综合分析和专题研究，查清采空区影响范围，确定方案；针对采空区对高铁的影响进行定量分析，并采取有效的防治措施。

Study on Mining Impacts at the Large Goaf Area of Mianyang—Luzhou High-speed Railway and Its Prevention Measures

In relation to Neijiang—Zigong—Luzhou Line of Mianyang—Luzhou High-speed Railway, which runs to Luoguan Mountain, can not avoid the large coal goaf area there, the high-speed railway alignment proposal with the most favorable geological conditions was ensured with selecting the minimized hazards to high-speed railway arising from mining impacts at the goaf area. Through collecting sufficient data, large area geological mapping contrast, comprehensive analysis and monographic study was conducted coupled with drilling and a variety of geophysical exploration results. The scope of influence of goaf was found out and the scheme was stabilized. In view of the influence of goaf on high-speed railway, quantitative analysis is carried out and effective prevention and control measures are taken.
