摘要:岩土工程地质钻探是利用人力、机械等手段,揭示地层层序、岩土工程特
征、认识地表以下地层或某一特定位置的情况或特点的一种勘探手段。其目的是
通过钻探取样,样品分析,现场工程地质测试等,以获取建筑基础的地质资料和
岩土层的各项参数,为选择修建地点,地基处理方式,基础形式,确定建筑物类
型,及制定合理的施工方法提供设计和施工依据。钻探得出的结果是否准确、真
实可靠直接影响着岩土工程勘察报告的分析和结论,因此掌握岩土工程勘察的钻
探技术具有重要的意义。本文首先分析了岩芯采取率的影响因素,然后从钻探设
备的选取,不同岩层的钻探方法等方面探讨了提高岩芯采取率和钻探技术的要
点。

Abstract: the geotechnical engineering geological drilling is utilizing
the means such as manpower, machinery, stratigraphic sequence,
geotechnical engineering characteristics, the deep understanding of
strata below the surface or in a particular location or characteristics
of a exploration method. Its purpose is through drilling sampling, sample
analysis, the engineering geology, testing, etc., for building foundation
of geological data and the parameters of rock and soil layers, to select
building sites, foundation treatment, foundation forms, determine the
structure types, and provide basis for design and construction for
reasonable construction method. Drilling results are accurate, true and
reliable directly affects the geotechnical engineering investigation
report of the analysis and conclusions, so the control of geotechnical
engineering drilling technology is of great importance. This article
first analyzes the influence factors of core take rate, and then from the
selection of drilling
