【摘要】：为了在不扰动滑坡结构稳定性的情况下更准确地揭示滑坡中滑带及滑体、滑床的岩土组成与结构特征及物理力学性质,在滑坡勘查中,往往用探井来采集土样并进行现场大剪切试验。目前,现场大剪切试验使用的大截面矩形探井,存在工程量大、安全性低等缺点,本论文结合工程中常用的矩形探井与圆形探井的优缺点分析,提出圆井-导洞型探井,并结合实例从经济性和安全性等方面与矩形探井分析比较,结果表明,该方法应用于实际更具优越性。
[Abstract]:In order to reveal more accurately the rock and soil composition, structural characteristics and physical and mechanical properties of sliding zone and body in landslide without disturbing the stability of landslide structure, in landslide exploration,The well is often used to collect soil samples and carry out field large shear tests.At present, the large section rectangular exploration wells used in the field large shear test have the disadvantages of large engineering quantity and low safety. This paper combines the advantages and disadvantages of the rectangular and circular exploration wells commonly used in engineering, and puts forward the round well and the guide hole type exploration well.The results show that this method is more effective in practice than that in rectangular exploration wells in terms of economy and safety.
