摘要
井间地震层析成象在环境工程勘探中的应用前景广阔,走时层析成象的射线追踪方法和高精度的解大型稀疏矩阵的方法是其中的关键。文中讨论了LSQR算法系列,数值模拟证明了它的优越性,最后应用于鹏飞大厦场地。
In environmental engineering prospecting,the crosshole seismic tomography is a promising method.The key to traveltime tomography are raypath tracing and alogrithm solving Sparse matrix equations.This paper discusses LSQR algorithm serials,of which high resolution was proved by numerical examples.Good results are demonstrated by actual data of Pengfei Building.
