【摘要】：为解决济南西客站片区辉长岩风化带准确划分的难题,本文通过文献、资料收集,归纳和总结辉长岩风化带的多方面研究成果,深入分析济南西客站片区辉长岩风化带的分带性及地域性,以济南恒大CBD项目现场为试验场地,运用工程地质学、岩石学、岩石波速测试法、风化系数法、点荷载试验法、标准贯入试验法和数字测井法等理论与试验方法对该问题进行了研究。通过钻探成果、野外鉴别和各种综合试验方法的对比分析,得出如下成果：1、岩石波速测试法、风化系数法、点荷载试验法、标准贯入试验法实测的试验数据,依据规范和野外岩芯鉴别基本上可以划分风化带,但都有局限性；2、数字测井法是对孔内数据图像进行解释分析,转换成各种物理量,更加贴切实际,定性定量的验证风化带划分的准确性。3、研究提出了采用数字测井法进行辉长岩风化带划分的参考建议指标。本文研究成果对于辉长岩风化带及其相近岩性风化带的准确划分,以及该片区超高层建筑物经济合理的地基持力层选择,具有重要的指导和实践意义。
[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.
