【摘要】：為了在不擾動滑坡結(jié)構(gòu)穩(wěn)定性的情況下更準確地揭示滑坡中滑帶及滑體、滑床的巖土組成與結(jié)構(gòu)特征及物理力學性質(zhì),在滑坡勘查中,往往用探井來采集土樣并進行現(xiàn)場大剪切試驗。目前,現(xiàn)場大剪切試驗使用的大截面矩形探井,存在工程量大、安全性低等缺點,本論文結(jié)合工程中常用的矩形探井與圓形探井的優(yōu)缺點分析,提出圓井-導洞型探井,并結(jié)合實例從經(jīng)濟性和安全性等方面與矩形探井分析比較,結(jié)果表明,該方法應(yīng)用于實際更具優(yōu)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.
