摘要

以提高电渗效率、改善电渗效果为目标，通过室内模型试验研究了长方形、梅花形和平行错位3种不同电极布置形式对电渗排水效果的影响。试验采用铝管电极，并保证各组试验处理面积、外加电压和处理时间一致。通过比较分析各试验排水量、电流降低率、裂缝开展和能耗系数得到以下结果：电极长方形布置时，裂缝最为规则、排水效果一般；电极平行错位布置时，排水效果最好，电流降低率最大，但从能耗系数的角度来评判仍然表现最好；电极梅花形布置时，裂缝开展最复杂，且产生了纵截面贯穿裂缝，严重影响了后期的电渗效果，但在裂缝大量开展前，其电流降低率极小。总结室内试验的结果，建议优先采用电极平行错位布置形式进行电渗处理。

Abstract

Aiming at effectively improving the electroosmotic efficiency and effects

the influence of three different arrangements of the electrodes

namely rectangular array

hexagonal array

and parallel and transposition array

on the effect of electroosmotic drainage through laboratory model tests is investigated. Aluminum tube electrodes are adopted; and the treated area

applied voltage and treated time are designed to assure the consistency among the three electrode arrangements. Drainage

the rate of current decrease

cracks on the soil and coefficient of energy dissipation are analyzed and compared after the tests. It is revealed that the cracks of rectangular array are regular and its drainage effect is ordinary. Parallel and transposition array has the maximum drainage

the largest rate of current decrease as well as the best performance based on the coefficient of energy dissipation. The cracks of hexagonal array are the most complex

which run through the lengthwise section and have a strong impact on the electroosmotic efficiency at later stages. Before the extensively developing of cracks

the rate of hexagonal array’s current decrease is very small. According to the results of laboratory tests

it is recommended to employ the parallel and transposition array primarily for electroosmotic treatment.
