Since it is hard for the available gauge of AC 4 Pole Method to measure the soil of high resistivity, two methods of expanding the measuring range are set forth in the paper, namely, Pole-Distance ( PD) regulating and Parallel Resistance ( PR) regulating. 由于现有的交流四极法仪表难以在高电阻率土壤中进行测量,为此,提出了两种扩大四极法测量电阻率范围的方法,即极距调整法和并联电阻法。
On the basis of the precisely proving about the principle of angle gauge, the errors about the design of pole type angle gauge were analyzed, and the revised method on the errors was provided. 本研究在严密证明角规测树原理的基础上,分析了杆式角规的设计误差,并提出修正方法,使角规原理与工具设计相统一,进一步完善了角规测树体系。
For in-depth analysis of loading transfer and bearing capacity property on pile body, preliminarily we had arranged rebar stress gauge on trial pole main reinforcement to measure pile body axial stress and inbuilted stress box under the pile to survey tip resistance. 为了进一步分析桩的荷载传递和承载力性状,预先在试验桩主筋上布置钢筋应力计以测量桩身轴向应力,在桩底埋设压力盒以测量桩端阻力。
