IN-SITU STRESS MEASUREMENT AND RESEARCH ON TECTONIC STRESS FIELD DISTRIBUTION LAW OF CHENGDU-LANZHOU RAILWAY

  • 摘要: 成兰铁路位于青藏高原东部边缘高山峡谷区,由于印度板块与欧亚板块碰撞,区域内构造变形强烈,构造应力场十分复杂。为研究成兰铁路工程区地应力分布规律及断层稳定性,在铁路沿线茂县、松潘县以及宕昌县境内4个深孔水压致裂地应力测量基础上,获得了不同位置区域地应力实测值的大小和方向,并建立工程区应力参数随深度分布规律。分析表明:工程区应力随深度变化呈现出较好的线性关系,在测试深度范围内,水平应力普遍高于垂直主应力,地应力值总体上属于中—高地应力级别,在750 m深度内,最大水平主应力达25 MPa,反映出工程区构造应力占主导地位,侧压系数随深度呈缓慢衰减趋势。成兰铁路在不同构造单元上最大水平主应力方向有所不同,在东昆仑断裂以北甘南块体内,最大水平主应力为北北东向,在东昆仑断裂以南川青块体内最大水平主应力为北西向。根据实测的地应力数据并结合库伦滑动摩擦准则,对工程区内的断层稳定性进行了分析。文中取得的认识对成兰铁路工程区的构造应力场、断裂活动性的研究以及隧道工程的建设具有重要的参考意义。
