在电法勘探中所应用的电测剖面,由于供电电极和测量电极间的相对位置不同,型式很多,各有各的优点和缺点,偶极电测剖面便是其中的一种。我队由于苏联专家的建议,自1958年起在黑龙江上、中游各个坝址的工程地质勘测工作中,开始应用了偶极电测剖面。结果指出这是比较优良的方法,能够达到多快好省的目的。对称电剖面 AMNB,三极联合剖面 AMNC,CMNB是目前最流行的装置型式。如果和这两种电测剖面比较,偶极电测剖面的优点表现在:①异常非常清晰,幅度最大。②能估计岩层的产状,并对薄岩层反应灵敏。③生产效率高。④能在一些特殊条件下解决问题。
Electric survey used in electrical prospecting section, due to the relative position between the power supply electrode and the measuring electrode, many types, each have their own advantages and disadvantages, dipole electrical measurement profile is one of them. As a result of the suggestion of Soviet experts, our team started to apply the dipole electric surveying section since 1958 in the engineering geological survey of each dam site in the upper and middle reaches of Heilongjiang. The results indicate that this is a relatively good method, to achieve the goal of more speed and better. Symmetrical electric profile AMNB, triode joint profile AMNC, CMNB is the most popular device type. If compared with these two electrical measuring sections, the advantages of the dipole electrical measuring section are as follows: ① The abnormality is very clear and the amplitude is the largest. ② can estimate the formation of rock formation, and thin rock reaction sensitive. ③ high production efficiency. ④ in some special conditions to solve the problem.
