矿用工字钢梯形棚顶梁防滑装置的研制 - Combined with the real example of monitoring pressure on the supporting system in the long span underground space of dk7 + 692 section at jiao - xin line of chongqing light railway , it is set forth the methods about choosing the support system and its parameter , digging methods of underground space , measuring and testing methods for the stress of the support system ; the testing results and variation pattern were analyzed for the stress of the initial supporting i - steel axial stress of bolt , stress of shot - concrete , supporting pressure of temporary i - steel and stress of steel of the second lining , then , the reason for deformation of the support system induced by sharp increase of i - steel was determined
摘要结合重庆市轻轨较新线大坪车站大跨度地下空间dk7 + 692断面施工支护体应力监测的工程实例，阐述了该大跨度地下空间支护结构的参数选择、地下空间的开挖方法、支护体结构的应力量测方法及测试手段；分析了支护体初期支护工字钢拱应力、锚杆轴力、喷射混凝土内应力、临时工字钢支撑应力、二次衬砌钢筋应力等测试结果和变化规律；确定了工字钢拱应力急剧增大而可能引起支护体系失稳的原因。
