【摘要】：本文通過對(duì)巖溶地區(qū)鉆孔灌注樁側(cè)(底)溶洞探測方法、巖溶地質(zhì)隱患、樁基穩(wěn)定性、巖溶勘測技術(shù)等研究,對(duì)巖溶地區(qū)的樁基設(shè)計(jì)、地質(zhì)隱患的評(píng)價(jià)體系以及綜合勘測技術(shù)等都有了更加全面的認(rèn)識(shí),并且針對(duì)出現(xiàn)地質(zhì)隱患的位置,根據(jù)樁基的類型提出相應(yīng)的處置方式,并結(jié)合工程實(shí)例進(jìn)行了詳細(xì)的闡述,具有較強(qiáng)的指導(dǎo)意義。在巖溶區(qū)進(jìn)行勘察時(shí),通過鉆探與物探等勘察方式綜合運(yùn)用,可以比較準(zhǔn)確、全面的反映出巖溶地質(zhì)情況,提高設(shè)計(jì)、施工的可靠性,以避免單一勘察所提供的不確切的結(jié)果給工程帶來不良的后果,確保工程達(dá)到經(jīng)濟(jì)合理的目的。文章中還詳細(xì)概括了樁基鉆孔溶洞特征,并通過各種影響因素對(duì)穩(wěn)定性進(jìn)行了全面的分析,還采用數(shù)值模擬的方法建模分析了建筑物基礎(chǔ)下或路基下溶洞頂板穩(wěn)定性。最后,通過對(duì)銅川市川口大橋的理論分析和工程實(shí)踐的研究,歸納總結(jié)出樁側(cè)(底)溶洞探測方法與選取,然后通過對(duì)各種溶洞處治技術(shù)的概括比較,得出切實(shí)可行的樁基鉆孔溶洞處治技術(shù)與方案,具有較強(qiáng)的參考價(jià)值。
[Abstract]:Based on the bored piles in karst area (bottom side) detection method of karst cave, karst geological hazards, pile foundation stability, the study of karst survey technology, the design of pile foundation in karst area, the geological hazard evaluation system and comprehensive survey technology have a more comprehensive understanding, and according to the geological hazard location, according to the pile foundation the type of the corresponding disposal methods, and described in detail with an engineering example, has a strong guiding significance. The investigation in karst area, through comprehensive drilling and geophysical survey and other methods, can accurately and fully reflect the karst geological conditions, improve the reliability of design, construction, to avoid a single the survey does not provide the exact result of adverse consequences for the project, to ensure that the project achieved the economic purpose. The article also summarizes the pile with the features of karst caves ,騫墮，
