簡介：隨著煤礦開采深度的增加，瓦斯涌出量增大，瓦斯災(zāi)害日趨嚴(yán)重同時地應(yīng)力增加，煤巖破碎量增大，地溫升高，煤自燃災(zāi)害也越發(fā)凸顯。兩種災(zāi)害共生的復(fù)合型災(zāi)害已成為煤礦重特大事故的普遍模式。因此，研究采空區(qū)瓦斯與煤自燃復(fù)合災(zāi)害的防治機理及技術(shù)具有十分重要的意義。瓦斯與煤自燃復(fù)合災(zāi)害特點的普遍共識是相互影響、相互制約，但現(xiàn)場實施時，要二者兼顧，易顧此失彼。因此，須依據(jù)瓦斯與煤自燃兩種災(zāi)害的特點以及各種災(zāi)害的防治方法，研究耦合影響的關(guān)鍵因素，確定防治機理與方法。由于瓦斯和煤自燃災(zāi)害防治方法的多樣性，相關(guān)研究僅針對某個實例進(jìn)行分析研究，沒有建立適合瓦斯與煤自燃復(fù)合災(zāi)害的預(yù)測、預(yù)報以及治理的綜合防治技術(shù)。本文從兩種災(zāi)害的特性和防治方法著手，認(rèn)為采空區(qū)瓦斯與煤自燃復(fù)合災(zāi)害的防治焦點在于控制采空區(qū)煤自燃，杜絕瓦斯爆炸的引火源，但防治重點是瓦斯。以自燃帶分布為耦合影響關(guān)鍵因素，在防治瓦斯的基礎(chǔ)上研究與防治煤自燃的相互作用和相互影響。瓦斯方面，依據(jù)開采條件和瓦斯涌出量預(yù)測，合理確定風(fēng)量、通風(fēng)形式和推進(jìn)速度，優(yōu)選抽采方法，高效治理瓦斯煤自燃方面，通過實驗確定煤自燃特性，在防治瓦斯的基礎(chǔ)上從控氧和控時間兩個方面制定防火方法。并由此確立了以預(yù)測、預(yù)報為主的復(fù)合災(zāi)害防治方法。復(fù)合災(zāi)害預(yù)測方面，依據(jù)現(xiàn)場實測建立CFD模型，進(jìn)行數(shù)值模擬預(yù)測研究，從通風(fēng)、抽采和防火三個方面分別模擬分析了不同風(fēng)量和通風(fēng)形式，各種大流量抽采方法，如尾抽、高抽巷、地面鉆井、高位鉆孔和埋管抽采，以及惰化防火對采空區(qū)自燃“三帶”分布的影響，從而確定防治自燃發(fā)火的最低推進(jìn)速度，并依此優(yōu)化通風(fēng)與瓦斯抽采方法，完善防火措施。復(fù)合災(zāi)害預(yù)報方面，通過實驗獲取指標(biāo)氣體和臨界溫度作為分析判定煤體自燃程度的依據(jù)，由束管監(jiān)測的氧濃度分布對數(shù)值模擬模型參數(shù)進(jìn)行修正?；趶?fù)合災(zāi)害防治方法，試驗研究了高瓦斯易自燃煤層惰化防火、高瓦斯強抽采工作面防火和高瓦斯易自燃工作面超大火區(qū)均壓滅火，驗證了復(fù)合災(zāi)害防治效果，建立了適合瓦斯與煤自燃復(fù)合災(zāi)害的預(yù)測、預(yù)報和治理的綜合防治技術(shù)。

簡介：武漢理1大學(xué)碩士學(xué)位論文摘要半剛性基層瀝青路面由于具有強度高、造價低、整體性及水穩(wěn)定性好等優(yōu)點，在我國公路建設(shè)中得到了廣泛的運用但半剛性基層在運營期間易產(chǎn)生干縮裂縫和低溫收縮裂縫，在交通荷載和溫度荷載的重復(fù)作用下，半剛性基層的這種收縮裂縫很容易擴展到瀝青面層而形成反射裂縫REFLECTIONCRACK。反射裂縫一旦產(chǎn)生，不僅影響路面的美觀和行車舒適性，更重要的是大大的縮短了路面的使用壽命。關(guān)于瀝青路面斷裂分析的理論及抗裂，國內(nèi)外已開展了大量的研究工作。由于斷裂力學(xué)較好的反映了結(jié)構(gòu)內(nèi)部存在的裂縫之類缺陷，因此在路面反射裂縫的分析方面得到了較好的應(yīng)用。目前采用斷裂力學(xué)對反射裂縫的研究主要集中在縫端應(yīng)力狀態(tài)及縫端應(yīng)力強度因子的計算上，通過對比不同防裂措施及材料的縫端應(yīng)力或應(yīng)力強度因子對防裂效果進(jìn)行計算比較而對疲勞壽命的計算及疲勞壽命與路面結(jié)構(gòu)參數(shù)的關(guān)系研究較少。本文采用斷裂力學(xué)有限元模型，通過疲勞斷裂分析，對溫度荷載作用下疲勞斷裂壽命進(jìn)行了計算同時對不同面層厚度和模量情況下疲勞斷裂壽命進(jìn)行了計算比較，為防裂材料和防裂結(jié)構(gòu)的選擇提供了理論依據(jù)。關(guān)于瀝青路面的防裂方法與材料，除了傳統(tǒng)的土工布和玻纖隔柵外，目前的研究主要集中在柔性中間夾層上，具體方法是在瀝青面層和半剛性基層之間設(shè)置一層彈性模量低，韌性好的材料作為應(yīng)力吸收層以吸收半剛性基層裂縫，目前這種方法是國內(nèi)外工程實踐中用得較多的一項工程措施。如，橡膠A青混凝土夾層和KOCH公司STRATA應(yīng)力吸收系統(tǒng)。本文在現(xiàn)有研究成果的基礎(chǔ)上對瀝青路面的反射裂縫機理進(jìn)行研究，同時制備防裂夾層新材料。本文的研究內(nèi)容主要包括以下兩個方面1本文在現(xiàn)有成果的基礎(chǔ)上，借助疲勞斷裂理論和有限單元法，研究半剛性基層瀝青路面反射裂縫溫度疲勞裂縫的擴展規(guī)律以及疲勞壽命的計算方法。分析不同面層結(jié)構(gòu)參數(shù)以及不同防裂材料與措施對反射裂縫溫度疲勞壽命的影響，從而為路面的結(jié)構(gòu)設(shè)計、路面開裂預(yù)測和合理選擇路面材料提供理論依據(jù)。2對夾層防裂效果進(jìn)行計算定量的計算，研究不同夾層模量對防裂效果的武漢理工大學(xué)碩士學(xué)位論文ABSTRACTTHEASPHALTPAVEMENTBASEDONSEMIRIGIDTYPEBASEHASGOTEXTENSIVEAPPLICATIONINOURCOUNTRYSROADCONSTRUCTIONBECAUSEOFITSADVANTAGESSUCHASHIGHINTENSITYLOWCOSTGOODPERFORMANCEOFGLOBALITYANDWATERSTABILITYBUTSEMIRIGIDTYPEBASECOURSEEASYTOPRODUCECONTRACTCRACKANDLOWTEMPERATURESHRINKCRACKDURINGRUNNINGBYTHEPERIODICALLYCHANGEOFTEMPERATUREANDREPEATEDTRAFFICLOADSANDTHISCRACKISEASYTOEXTENDTOTHESURFACEITSSOCALLEDREFLECTIONCRACKTHEREFLECTIONCRACKNOTONLYAFECTTHEROADAPPEARANCEANDDRIVECOMFORTANDTHEMOSTIMPORTANTTHINGISTHATGREATLYSHORTENSTHESERVICELIFEOFROADSURFACEMANYRESEARCHESHASLAUNCHEDABOUTTHETHEORYOFROADCRACKANDTHEMATERIALANDMETHODOFANTICRACKBOTHATHOMEANDABROADBECAUSETHEFRACTUREMECHANICCANWELLREFLECTTHEEXISTINGCRACKINTHEPAVEMENTSOITHASGOTBETERAPPLICATIONINTHEANALYSISOFREFLECTIONCRACKOFPAVEMENTPRESENTRESEARCHADOPTINGFRACTUREMECHANICMAINLYCONCENTRATEDONTHESTRESSSTATEANDTHESTRESSINTENSITYFACTORONCRACKTIPTHROUGHCOMPAREWITHTRESSORSTRESSINTENSITYFACTORTOEVALUATETHEANTECRACKEFECTBYDIFFERENTANTICRACKMATERIALSORMETHODSLESSSTUDYHASBEENDONEABOUTFATIGUELIFEANDTHERELATIONSHIPABOUTFATIGUELIFEANDROADSTRUCTUREPARAMETERTHISPAPERADOPTINGFRACTUREMECHANICSFINITEELEMENTMODELANDTHETHEORYOFFATIGUEFRACTUREMECHANICSEXPATIATESTHETHEORYANDCOMPUTATIONALMETHODOFREFLECTIONCRACKSFATIGUELIFEUNDERTEMPERATURELOADSATTHESAMETIMECALCULATESANDANALYZESTHEINFLUENCEFACTORSOFREFLECTIONCRACKSFATIGUELIFETOOFFERTHETHEORETICALFOUNDATIONFORANTICRACKMATERIALANDSTRUCTUREMANYMATERIALSHASBEENADOPTEDTOREDUCEREFLECTIONCRACKSUCHASGEOTECHNOLOGICALGRIDSORNETSPRESENTRESEARCHESAREMAINLYCONCENTRATEDONTHEFLEXIBLEINTERLAYERTHECONCRETEMETHODISTOSETUPAINTERLAYEROFLOWELASTICMODULUSANDGOODTOUGHNESSBETWEENPAVEMENTANDSEMIRIGIDBASECOURSEINORDERTOABSORBTHECRACKTIPSTRESSTHEMETHODHASWILDLYUSEDINPROJECTPRACTICEATPRESENTSUCHASRUBBERASPHALTCONCRETEANDSTRATASTRESSABSORBEDSYSTEMEXPLOITEDBYKOCHCOMPANYTHISPAPERRESEARCHONTHEMECHANISMOFTHEREFLECTIONCRACKONTHEBASISOFFORMERSTUDYANDPREPARENEWTYPEOFSTRESSABSORBEDMATERIALTHISPAPERMAINLYINCLUDETWOASPECT1THISPAPERSTUDIESTHEREFLECTIONCRACKSEXPANSIONLAWANDCOMPUTINGMETHODOFFATIGUELIFEWHENTEMPERATURECHANGESTHEINFLUENCEOFPARAMETERANDDIFERENTANTICRACKMATERIALANDMETHODONANALYSISANDTHETHEORETICALFOUNDATIONFORANTICRACKMATERIALFATIGUELIFESTRUCTUREHASBEENANDSTRUCTURECANBE
