【摘要】：為解決濟(jì)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(jì)南西客站片區(qū)輝長巖風(fēng)化帶的分帶性及地域性,以濟(jì)南恒大CBD項(xiàng)目現(xiàn)場(chǎng)為試驗(yàn)場(chǎng)地,運(yùn)用工程地質(zhì)學(xué)、巖石學(xué)、巖石波速測(cè)試法、風(fēng)化系數(shù)法、點(diǎn)荷載試驗(yàn)法、標(biāo)準(zhǔn)貫入試驗(yàn)法和數(shù)字測(cè)井法等理論與試驗(yàn)方法對(duì)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(yàn)方法的對(duì)比分析,得出如下成果：1、巖石波速測(cè)試法、風(fēng)化系數(shù)法、點(diǎn)荷載試驗(yàn)法、標(biāo)準(zhǔn)貫入試驗(yàn)法實(shí)測(cè)的試驗(yàn)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(cè)井法是對(duì)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(shí)際,定性定量的驗(yàn)證風(fēng)化帶劃分的準(zhǔn)確性。3、研究提出了采用數(shù)字測(cè)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(duì)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(jì)合理的地基持力層選擇,具有重要的指導(dǎo)和實(shí)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.
