摘要
介绍了爆破挤淤法修筑海堤的基本原理和施工方法,以及钻探、探地雷达、地震映像和面波检测方法的基本原理。在两个工点进行了检测对比试验,结果表明四种检测方法各有优缺点。钻探检测方法结果直观,但检测速度慢,成本较高;探地雷达检测速度快、精度高,但检测深度有限;地震映像精度较低,但检测深度可以深达100m;面波检测可以测得地层的面波波速,但对深度的分辨率较低。通过将四种检测方法组合,总结出了一套行之有效的综合检测方法。
The principle and construction procedure of explosive replacement method as well as the principle of boring, ground penetrating radar （GPR） , seismic imaging and surface wave inspecting techniques were introduced. Two inspecting comparing experiments were respectively conducted at two sites. The results indicated that the four inspecting methods have merits and demerits. The boring method can obtain directly perceived result but costs a lot and the inspecting speed is very low. The inspecting speed and precision of GPR are very high, but the penetrating depth is limited. The precision of seismic imaging method is relatively low, but the inspecting depth can be as high as 100m. The surface wave velocity of the stratum can be obtained from the surface wave inspecting result, but the depth precision is low. Through combining the four methods, a useful comprehensive inspecting method was put out.
