摘要:露天礦邊坡穩(wěn)定性監(jiān)控預(yù)報(bào)技術(shù)研究,對(duì)滑坡地質(zhì)災(zāi)害防控具有重要意義。以滑體、滑床和監(jiān)控錨索相互
作用力學(xué)原理為理論基礎(chǔ),提出滑體和滑床相對(duì)運(yùn)動(dòng)狀態(tài)的力學(xué)監(jiān)測原理,把多因素監(jiān)測變?yōu)閱我换瑒?dòng)力力學(xué)量
監(jiān)測,給出滑動(dòng)力與監(jiān)控預(yù)緊力的關(guān)系。通過滑坡物理模型試驗(yàn)得出,在滑坡發(fā)生前,邊坡巖體內(nèi)應(yīng)力會(huì)連續(xù)發(fā)
生變化,當(dāng)滑動(dòng)力大于抗滑力后,邊坡巖體會(huì)發(fā)生變形和滑動(dòng),且捕捉邊坡巖體 內(nèi)應(yīng)力的變化優(yōu)于對(duì)巖體位移的
監(jiān)測。基于上述原理和試驗(yàn)結(jié)果,開發(fā)了滑坡地質(zhì)災(zāi)害遠(yuǎn)程監(jiān)測預(yù)報(bào)系統(tǒng),實(shí)現(xiàn)攝動(dòng)力動(dòng)態(tài)變化的遠(yuǎn)程實(shí)時(shí)監(jiān)測。
提出4種監(jiān)測預(yù)警模型,通過對(duì)露天礦山邊坡等的現(xiàn)場實(shí)踐應(yīng)用,該監(jiān)控新技術(shù)成功地進(jìn)行邊坡穩(wěn)態(tài)實(shí)時(shí)監(jiān)控和
預(yù)測預(yù)報(bào)。
