【摘要】：在西沙琛航島地質(zhì)調(diào)查中,應(yīng)用數(shù)字鉆孔攝像技術(shù),通過引入RMDI法開展對珊瑚礁完整性的分析研究,結(jié)合巖體分級標(biāo)準(zhǔn),構(gòu)建珊瑚礁完整性指數(shù)與珊瑚礁完整程度的對應(yīng)關(guān)系,實現(xiàn)針對珊瑚礁完整性的工程評價。通過對CK1孔和CK2孔的攝像勘察和統(tǒng)計分析,按照基于RMDI法的珊瑚礁完整程度分級標(biāo)準(zhǔn),對兩孔進(jìn)行珊瑚礁完整性評價,與實體巖芯保持一致,并估算出兩孔之間珊瑚礁的巖體完整程度。研究結(jié)果表明:在珊瑚礁完整性評價中,按珊瑚礁完整性指數(shù)構(gòu)建的分級標(biāo)準(zhǔn)是可行的;按RMDI法建立的珊瑚礁完整程度是準(zhǔn)確的;針對珊瑚礁的鉆孔攝像勘察和統(tǒng)計分析具有重要意義。
[Abstract]:In the geological survey of Xisha Chen Island, digital borehole camera technique was used to analyze the integrity of coral reef by introducing RMDI method, and combined with rock mass classification standard. The relationship between the integrity index of coral reef and the integrity degree of coral reef was established to realize the engineering evaluation of the integrity of coral reef. The camera survey and statistical analysis of CK1 hole and CK2 hole were carried out. According to the classification standard of coral reef integrity based on RMDI method, the coral reef integrity evaluation of the two holes is consistent with the solid core. The results show that the classification criteria based on the coral reef integrity index are feasible in coral reef integrity evaluation. The integrity of coral reefs established by RMDI method is accurate. Borehole camera survey and statistical analysis of coral reefs are of great significance.

【正文快照】： 造礁石珊瑚屬能分泌碳酸鈣形成骨骼和外殼、行群體固著生活的腔腸動物的石珊瑚目Scleractinia[1]。珊瑚礁是由造礁石珊瑚群體死后遺骸經(jīng)過破壞、搬運、堆積及膠結(jié)等作用而形成的特殊巖土體[2]。珊瑚從古生代初期開始繁衍,一直延續(xù)至今。珊瑚屬種多,演化快,常成為劃分地層的依，
