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 摘要結(jié)合重慶市輕軌較新線大坪車站大跨度地下空間dk7 + 692斷面施工支護體應(yīng)力監(jiān)測的工程實例,闡述了該大跨度地下空間支護結(jié)構(gòu)的參數(shù)選擇、地下空間的開挖方法、支護體結(jié)構(gòu)的應(yīng)力量測方法及測試手段;分析了支護體初期支護工字鋼拱應(yīng)力、錨桿軸力、噴射混凝土內(nèi)應(yīng)力、臨時工字鋼支撐應(yīng)力、二次襯砌鋼筋應(yīng)力等測試結(jié)果和變化規(guī)律;確定了工字鋼拱應(yīng)力急劇增大而可能引起支護體系失穩(wěn)的原因。
Tensile stress field would appear in the proximity of arched vault after excavation , slacking of surrounding rock and subsequent dropping of blocks of rock from such area would possibly occur at any time in the context of extra - shallow depth . so i - steel arched support must be erected to provide against possible block dropping and be integrated into a ring with that of pilot tunnels on both sides 拱頂在核心土開挖后,在一定范圍內(nèi)出現(xiàn)拉應(yīng)力區(qū),在超淺埋情況下極容易掉塊和發(fā)生圍巖松馳,因此核心土必須邊開挖邊架設(shè)工字鋼拱架,使之與左右導(dǎo)洞拱頂工字鋼形成整體。
