Firstly, based on the parameters of apparent resistivity, apparent chargeability, half decay time, decay rate and the relativity of water inflow, it uses multivariate regression method to establish the prediction model. Then, through the variance test, it shows that it is feasible to use the model to predict the water content quantitatively in the exploration region.

基于视电阻率、视极化率、半衰时、衰减度等参数和涌水量的相关性，利用多元回归方法建立地下水量预测模型，通过方差检验，说明用此模型对勘探区内进行含水量的定量预测是可行的。

This paper calculates the 3D magnetotelluric responses in homogeneous half space using integral equation method and apply the damped least square method to inverse the resistivity of 3D model.

采用积分方程法计算均匀半空间中三维异常体的大地电磁响应，然后利用阻尼最小二乘法反演得到地下三维异常体电阻率分布。

Suitable conditions for subsurface irrigation most often occur on glacial outwash plains, terraces, or deltas in humid or sub-humid areas.

In this paper, the analytical expressions of seismic input for homogeneous elastic half-space are first derived in oblique incidence of plane SV-wave, and then a finite element model for a real hydropower cavern group composed of main powerhouse- transformer chamber- tailrace surge tank cavern is created. Characteristics of seismic responses such as displacement, acceleration and stress are studied in detail at different incidence angles and some results are compared with those given by the literature.

本文首先推导了平面SV波斜入射下均质弹性半无限空间的地震动输入表达式，然后建立了某水电站主厂房室-主变室-尾水调压室等构成的地下洞室群有限元模型，详细研究了不同入射角度下各洞室的位移、加速度、动应力等地震反应特点，并与文献进行了对比。
