背景技术 Background technique

[0002] 在地质勘查领域,通常会使用到激发极化法来根据岩、矿石的激发极化效应W便寻找金属矿物和解决水文地质、工程地质等问题。 [0002] In the field of geological prospecting, often used to induced polarization method according to Rock, the induced polarization effect of W will look for metal ore minerals and resolve hydrogeology, engineering geology and other issues. 激发极化法可分为时间域激发极化法和频率域激发极化法两种类型,其中Beam超前地质预测是W频率域激发极化法为基础,是TBM 隧道掘进中常用的一种超前地质预报方法,其通过采用适当的超前地质预测技术,有利于探明前方地质情况,做好相应的防护措施,从而确保施工安全正常进行。 Induced polarization method can be divided TBM tunneling in common kind of lead time domain induced polarization method and frequency-domain induced polarization method of two types, which are W Beam advance geology prediction frequency-domain induced polarization method is based on the geological prediction method by the use of appropriate advance geology prediction techniques conducive proven geological conditions in front, make the appropriate protective measures to ensure the safety of construction work correctly.

[0003] Beam超前地质体预测在我国尚处于研发初步阶段,为有效提高测试准确性,亟待改进和提高其测试技术。 [0003] Beam advance geological prediction in China is still in the preliminary stages of development, in order to improve the accuracy of the test, the test needs to improve and enhance their technology. 目前,现有技术中的Beam法是将供电电极安装在TBM护盾上,整个设备作为电流发射源与周围介质接触,并直接测量护盾电压。 Currently, the prior art method is to supply Beam electrode shield mounted on the TBM, the entire device as a current source emitter in contact with the surrounding medium, and the shield voltage is measured directly. 由于通电情况下护盾与围岩之间存在着很大的面极化效应,而运种面极化效应相对于地质体总极化效应来说较大,运种面极化电压又是直接叠加在护盾与另一端供电电极之间电回路的电压上,因此护盾的面极化会直接影响到超前探测的准确性。 Between the shield and the presence of surrounding rock with power are significant side effects of polarization, and polarization effects transported species relative to the total surface polarization effect is larger geological, surface transport types polarization voltage is directly superimposed on the voltage between the shield electrode and the other end of the power supply circuit, so the shield surface polarization will directly affect the accuracy of advanced detection. 现有的面极化实验测试都是在供电电极和液体之间的界面进行,而对于固态试样与供电电极之间的面极化效应测量,由于在固体试样中测量电极不可能像在液体中那样自由移动,因此不能无限接近固体供电电极表面,造成现有的面极化实验测试方案难W较好地符合实际工况。 Existing experimental test plane polarization is at the interface between the electrode and a liquid carried, and for solid sample measurement surface polarization effect between the electrodes and the power supply, since the measuring electrode in a solid sample can not, as in liquids as free movement, and therefore can not be infinitely close to the solid surface of the powered electrode, causing the plane of polarization of the existing experimental test program is difficult W to better meet the actual working conditions.
