摘要
岩土工程勘察是工程建设的重要环节之一,充分、科学的勘察工作可以为项目评估、设计、施工提供可靠的岩土工程参数和地质资料,对节约投资、优化设计、项目顺利开展起到重要的作用。勘察钻探施工是岩土工程勘察工作的基础。广西地区在历史上数次受构造运动的影响,在此基础上发育的破碎、较破碎地层存在一定的普遍性,对岩土工程勘察施工造成了一定的困难。在该客观条件下的岩土工程勘察的钻探施工,易发生塌孔、钻杆弯曲等不利情况,往往是岩土工程勘察工作是否能够顺利实施的关键。论文以广西地区某高速公路岩土工程勘察项目为载体,围绕复杂构造应力作用下破碎地层钻探技术展开探讨。
Geotechnical engineeringinvestigationis one oftheimportantlinksin engineeringconstruction.Full and scientificinvestigation can provide reliable geotechnical engineering parameters and geological data for project evaluation,design and construction,it plays an important role in saving investment,optimizing design and carrying out the project smoothly.Exploration drilling construction is the foundation of geotechnical engineeringinvestigation.The impact of several tectonic movementsin the history of Guangxi region,many of which have complex tectonic history,on the basis of which there is a certain degree of universality in the development of broken and relatively broken strata,which causes certain difficulties in geotechnical engineering investigation and construction.Under this objective condition,the drilling construction of geotechnical engineering investigation is prone to collapse and drill pipe bending,which is often the key to the successful implementation of geotechnical engineeringinvestigation.This paperwilltake a highway geotechnical engineering exploration projectin Guangxi asthe carrier,and discussthe drillingtechnologyof fractured strata under complextectonic stress.
