摘要
根据堤坝软弱层的物性特点，选用国内外先进物探仪器和方法技术，通过测试和对比分析，确定用瞬态面波法可以很好地探到堤坝相对强度和软弱层分布范围。根据其方法原理，结合地震学中有关计算方法。编制完成了瞬态面波计算解释软件，通过不断完善软件和改进仪器；最终使得这一方法在探测堤坝软弱层的过程中取得显著效果。文中首先对瞬态而波法的基本原理进行了介绍，然后讨论了野外工作方法、仪器选择和信号处理等内容，最后通过应用实例验证了所述方法和软件的正确性与实用性。
ccording to soft layer characters,applying the advanced techniques and detection instruments at home and abroad,the transient state surface wave method is decided to be able to detect the relative strength of dam and dyke,as well as distribution range of soft layer through detection and comparative analysis. Comply with its principles and combine with seismological calculation method,the software for calculation by transient state surf see wave method is drawn up and perfectly applied in soft layer detection and remarkable success has been achieved through improving the software and instruments. The basic principles of transient state surf see wave method is introduced in the paper,then the field working way,instrument choice and signal treatment are discussed,and finally the accuracy and capability of the mentioned method software are checked by actual examples.
