【摘要】：建立在錨網(wǎng)噴支護(hù)和鋼管混凝土支架高強(qiáng)度支護(hù)基礎(chǔ)上,提出巷道承壓環(huán)強(qiáng)化支護(hù)模型及理論,闡述了承壓環(huán)的概念,建立承壓環(huán)的力學(xué)模型,并對承壓環(huán)結(jié)構(gòu)的承栽能力進(jìn)行理論分析,最后對深井軟巖巷道承壓環(huán)進(jìn)行分類并提出相應(yīng)的支護(hù)設(shè)計(jì)方法,巷道承壓環(huán)強(qiáng)化支護(hù)理論作為新的深井巷道支護(hù)概念,對于深井軟巖巷道支護(hù)機(jī)理的分析和實(shí)際支護(hù)工作具有重要意義。
[Abstract]:On the basis of bolt-mesh shotcreting support and high strength support with concrete filled steel tube support, this paper puts forward the model and theory of strengthened support for roadway bearing ring, expounds the concept of pressure ring, and establishes the mechanical model of pressure ring. The bearing capacity of bearing ring structure is analyzed theoretically. Finally, the bearing ring of soft rock roadway in deep shaft is classified and the corresponding supporting design method is put forward. The theory of strengthened supporting ring in roadway is regarded as a new concept of roadway support in deep well. It is of great significance to analyze the supporting mechanism of soft rock roadway in deep well and to support it in practice.
