| 摘 要： | 为了对多条二维剖面资料进行统一分析和解释,本文考虑了各剖面交点处的约束条件,通过建立统一的偏导矩阵,将各剖面资料联立求解.利用该方法对中国地震局地球物理勘探中心在首都圈内6条人工地震宽角反射/折射剖面资料进行了重新处理和解释,得到该地区的地壳三维速度结构和构造特征.在此基础上,结合其他地球物理研究成果,确定了壳内存在的4处低速层（体）的空间范围及断裂的走向.

| Abstract: | In order to carry out an unified analysis and interpretation of the 2 D data from multiple profiles, constraints at the intersecting points of the profiles are taken into account. A solution of simultaneous equations with integrated data from all the profiles is accomplished by constructing a unified matrix of partial derivatives. The method is used to reprocess and reinterpret data from 6 wide angle reflection/refraction DSS profiles conducted in the Capital Area by the Research Center of Exploration Geophysics, China Seismological Bureau. As a result, 3 D velocity structures and tectonic characteristics of the crust in this area are obtained On this basis, and in the light of results by other geophysical techniques, the spatial scope of 4 crustal low velocity layers （bodies） and fault strikes are determined. |
