介绍了探测地质体结构的一般方法，重点介绍了爆破地震波的特征及地震波的探测方法。又对最近发展起来的面波勘探技术做了分析，重点论述了瞬态瑞利波频散特性及其应用。在此基础上，实验了一种可以控制的爆破地震波震源，该震源利用水介质的均匀性及各向同性、不可压缩等特点，减少了爆炸冲击波对周围岩体介质的损坏，又保持了爆炸波功率大，能够提供尖锐的脉冲信号，频域范围大的特点，从而改变了爆破地震波震源不能重复和难以总结其规律的状况。利用瑞利波探测技术和可控爆源，对茅坪滑坡体进行了地质体结构探测，并对其地质体的分层特性做了详细分析，与钻孔勘探结果和挖竖井探测结果比较，二者有较好的一致性。说明结合瞬态瑞利波分析方法，该可控震源在地质体结构探测中有实际的应用价值。

The paper introduces general methods of surveying geological body structure,highlighting on char-acteristics of blasting seismic wave and the method of surveying seismic wave.In addition,it analyzes the technology of surveying by surface wave which has been developed recent years,highlighting on discussing the characteristics of transient Rayleigh wave and its application.On the bases,a blasting seismic source which can induce controllable seismic wave is tested.The blasting seismic source makes use of the homogeni-zation,isotropy,incompressibility of water;and it reduces the damage around rock induced by explosion wave;and it keeps the character of big power of blast wave,and can provide sharp pulsing signal and great frequency domain.So this blasting seismic source changes the characteristics which customary blasting seis-mic source can not be repeated and it is difficult to seek the rule of blasting seismic wave.The paper makes use of the technology of Reyleigh wave surveying to study the geological body structure of Maoping landslide mass.It also analyzes the layered characteristics of landslide mass.The analytical results accord with the re-sults of surveying by drilling and sinking a shaft.It is shown that the controllable blasting seismic source can be used in surveying geological body structure with the method of transient Rayleigh wave surveying.
