中文摘要：
基于回转钻探和静力触探试验的综合优势,开发并进行系统地旋进式触探试验,在室内试验和理论推导的基础上进一步验证。从旋进式触探机制入手,根据切削、静压及钻压作用过程建立旋进式触探试验参数钻压、扭矩与每转进给量之间的关系曲线,结合室内试验成果进而以曲线斜率和钻削理论为依托推导出岩石的抗压强度、弹性模量、内摩擦角及黏聚力的计算公式。以粉煤灰砌块旋进式触探试验成果为例,按上述方法计算试样4大基本力学参数,与试验实测值进行验证。结果表明计算值与室内实测的基本力学参数值比较接近,论证了该方法的可行性和后续研究的可期待性。
英文摘要：
A system of rotary penetration was developed combining the advantage of rotary drilling and static penetration with verifications from laboratory tests and theoretical study. According to the mechanism of rotary penetration,the relationships between the drilling pressure,the torque and the feed per rotation in the processes of cutting,the direct pressing and the bit pressing have been found. The formulae for the compressive strength,the elastic modulus,the internal friction angle and the cohesion of rock were derived on the basis of laboratory test results. The method was applied to the fly ash blocks and the measured results were in good agreement with the calculated ones,which indicated the feasibility of the proposed method.
