通过对煤系地层中软岩与软岩工程稳定性常用控制方法和存在问题的系统研究,提出了采用电化学方法改性粘土类软岩以实现其长期稳定性的新思路。对粘土类软岩的电化学改性机理进行基础理论分析;开展了电化学改性的初步试验研究,试验结果表明:在直流电场作用下,电化学方法能够进一步加固煤系地层中的粘土类软岩,提出了利用铁质锚杆对软岩进行电化学改性的建议。
Through the systematic study on the common control methods and existing problems of soft rock and soft rock engineering stability in coal measures, a new idea of using electrochemical method to modify clay soft rock to achieve its long-term stability is proposed. The basic theoretical analysis of the mechanism of electrochemical modification of clay soft rock was carried out. The preliminary experimental study of electrochemical modification was carried out. The experimental results show that under the action of DC electric field, the electrochemical method can further reinforce the clay Soft rock, put forward the suggestion of using iron anchor to electrochemically modify soft rock.
