白垩纪新的应用地质学的建立是一个学术研究和向业界学习的双向过程，其中地质学的哪些方面对建设项目和水文地质学具有特别重要的意义。第11次Glossop讲座探讨了思想的发展，这些思想导致了英国粉笔的重新绘制，对应用的岩石地层学和裂缝地层学的认识，对物质行为的更好理解，以及可以建立数字模型的改进的概念模型。在为白垩岩的描述和分类获取更可靠的信息的背景下，考虑到技术的进步，特别是钻孔照相机测井和地球物理测井。用于评估粉笔工程各个方面的施工项目包括：评估A26 Cuilail隧道(刘易斯隧道和A27 Southwick隧道)上隧道的岩体描述和分类；A27布莱顿旁路岩溶特征方面的土方工程；肖勒汉姆港废水隧道内隧道掘进机穿过火石挖掘的风险分析；认识不同白垩岩形成对隧道和竖井的影响；处理A303巨石阵隧道意外地质问题；开发和应用在英吉利海峡隧道铁路线、横贯铁路线以及伦敦东部的泰晤士河和Lee隧道上的钻孔取芯测井技术。从建造过程中的发现到“纯粹的”地质学的反馈被证明对该学科在英国的发展至关重要。
The building of a new applied geology for the Chalk has been a two-way process between academic research and learning from industry which aspects of the geology are of special importance to construction projects and hydrogeology. The 11th Glossop Lecture explores the development of ideas that have led to the remapping of the English Chalk, recognition of an applied lithostratigraphy and fracture stratigraphy, greater understanding of material behaviour and enhanced conceptual models on which numerical models can be built. Advances in technology, particularly borehole camera logs and geophysical logs, are considered in the context of acquiring more reliable information for the description and classification of chalk. Construction projects used to assess aspects of chalk engineering include assessing rock mass descriptions and classifications for tunnelling on the A26 Cuilfail Tunnel, Lewes, and A27 Southwick Tunnels, Brighton; earthworks in relation to karst features on the A27 Brighton Bypass; risk analysis in relation to tunnel boring machine tunnelling through flints in the Shoreham Harbour Waste Water Tunnel; recognizing the impact of different Chalk formations on tunnels and shafts on the Brighton and Hove Stormwater Tunnel; dealing with unexpected geology on the A303 Stonehenge Tunnel; developing and applying techniques to borehole core-logging on the Channel Tunnel Rail Link, Crossrail and the Thames and Lee tunnels in east London. The feedback from discoveries made during construction to ‘pure’ geology is shown to be crucial to the subject’s development in the UK.
