【摘要】：為解決濟南西客站片區(qū)輝長巖風(fēng)化帶準(zhǔn)確劃分的難題,本文通過文獻(xiàn)、資料收集,歸納和總結(jié)輝長巖風(fēng)化帶的多方面研究成果,深入分析濟南西客站片區(qū)輝長巖風(fēng)化帶的分帶性及地域性,以濟南恒大CBD項目現(xiàn)場為試驗場地,運用工程地質(zhì)學(xué)、巖石學(xué)、巖石波速測試法、風(fēng)化系數(shù)法、點荷載試驗法、標(biāo)準(zhǔn)貫入試驗法和數(shù)字測井法等理論與試驗方法對該問題進(jìn)行了研究。通過鉆探成果、野外鑒別和各種綜合試驗方法的對比分析,得出如下成果：1、巖石波速測試法、風(fēng)化系數(shù)法、點荷載試驗法、標(biāo)準(zhǔn)貫入試驗法實測的試驗數(shù)據(jù),依據(jù)規(guī)范和野外巖芯鑒別基本上可以劃分風(fēng)化帶,但都有局限性；2、數(shù)字測井法是對孔內(nèi)數(shù)據(jù)圖像進(jìn)行解釋分析,轉(zhuǎn)換成各種物理量,更加貼切實際,定性定量的驗證風(fēng)化帶劃分的準(zhǔn)確性。3、研究提出了采用數(shù)字測井法進(jìn)行輝長巖風(fēng)化帶劃分的參考建議指標(biāo)。本文研究成果對于輝長巖風(fēng)化帶及其相近巖性風(fēng)化帶的準(zhǔn)確劃分,以及該片區(qū)超高層建筑物經(jīng)濟合理的地基持力層選擇,具有重要的指導(dǎo)和實踐意義。
[Abstract]:In order to solve the problem of accurately dividing the weathering zone of gabbro in Xi Ke Station, Jinan, this paper summarizes and summarizes the various research results of the weathering zone of gabbro through literature and data collection. The zonation and regionality of gabbro weathering zone in Xi Ke Station, Jinan are analyzed in depth. Taking the site of Jinan Hengda CBD Project as test site, engineering geology, rock wave velocity test, weathering coefficient method and point load test method are used. The standard penetration test method and digital logging method are used to study this problem. Through drilling results, field identification and comparative analysis of various comprehensive test methods, the following results were obtained: 1, rock wave velocity test, weathering coefficient method, point load test method, standard penetration test method. According to the criterion and field core identification, weathering zone can be divided basically, but both have limitation. Digital logging method is used to interpret and analyze the data image in the hole and convert it into various physical quantities, which is more practical. The accuracy of weathering zone division is verified qualitatively and quantitatively, and a reference index for the classification of weathering zone of gabbro by digital logging method is proposed. The research results in this paper have important guiding and practical significance for the accurate division of the gabbro weathering zone and its adjacent lithologic weathering zone and for the economical and reasonable foundation bearing layer selection of the super-tall buildings in this area.
