摘要以测得的误差声速剖面作为初始猜测值，利用多波束记录到的波束传播时间和波束角等信息，通过广义线性反演得到一个与实际声速剖面比较接近的声速剖面，这有助于减少声速剖面的误差。 - Multi - channel deconvolution , based on multi - channel signal analysis , is presented to recover receiver function from three - component teleseismic p waveforms clustered within certain backazimuth and epicenter distance , to increase the resolution of receiver function . wavelet inversion is also introduced to broadband receiver function , to solve for nonuniqueness cased by linear approximation of nonlinear problem , and broadband receiver function is decomposed into multi - resolution versions , and the inversion result for the low - resolution version is iteratively taken as the initial model for the high - resolution , and gradually obtain the inversion model for broadband receiver function
为克服广义线性反演对初始模型的依赖性，并保持其快速收敛的特点，本文首次将小波变换引入到接收函数波形反演，将接收函数分解到不同的分辨尺度上，分别进行广义线性反演，并将低分辨率的反演结果作为高分辨率反演的初始模型，渐近地获取宽频带接收函数的模型，克服了非线性问题线性化带来的非唯一性。 - On the basis of displacement - time series of the slope , a nonlinear dynamic model is set up according to backus generalized linear inversion theory in this paper . due to the equivalence beween autonomous gradient system and catastrophe model , a standard cusp catastrophe model can be obtained through variable substitution . the method is used in analysis of displacement data of huangci landslide and wolongsi landslide and in understanding how slopes evolve before sliding . the result shows that the nonlinear dynamic model can make satisfactory prediction result . is it most important that there is a sudden fall of d , which indicates the occurrence of catastrophe ( when d = 0 )
