本文解释了横穿钱塘凹陷、西湖凹陷直至钓鱼岛隆褶带长约147km的TB地震剖面；针对东海陆架盆地自古新世以来经历了断陷一被动大陆边缘一挤压一拗陷多时期构造相叠加的特点，建立了拗陷模型、剖面平衡模型和断陷模型。利用作者开发的模拟软件包，计算恢复了各时期的地层原始厚度，再现了拗陷的沉降压实过程；由等面积和关键层平衡结合的方法，实现了T40－T20间挤压构造的复原，得到了平衡剖面并计算了各层面的缩短量；根据生长断裂信息反演犁式断裂在深部延伸的情况并计算了在拉张过程中上盘的位移场和运动轨迹；得到古新世时期从西湖凹陷至钓鱼岛隆褶带的拉张量约为10．4km。通过串接组合拗陷模型、剖面平衡模型和断陷模型，实现了断一挤一拗转化叠加的模拟，再现整个构造沉降发展史，并以一定时间间隔的图形形式表达了模拟的动态结果。
This paper explains the TB seismic section across the Qiantang sag and the Xihu sag up to the Diaoyu island fold belt about 147km long. For the East China Sea shelf basin, since the Paleocene, the tectonic phase superimposed on the fault-passive continental margin has been experienced Characteristics, established a depression model, section balance model and fault depression model. Using the simulation software package developed by the author, the original thickness of the strata was calculated and restored, and the settlement and compaction process of the depression was reproduced. By the combination of equal area and key strata, the reconstructions of the compression structure between T40 and T20 , The equilibrium section was obtained and the shortened amount of each layer was calculated. Based on the growth fracture information, the plow fracture in the deep part was inverted and the displacement field and motion trajectory of the upper plate during tensioning were calculated. The tension from the Xihu Depression to the Diaoyu Island Longfold Belt is about 10.4km. By cascading the combination of depression model, section balance model and fault depression model, the simulation of the superimposition of fault-extrusion-depression transformation is realized, and the entire history of structural settlement is reproduced. The dynamic results of the simulation are expressed in graphic form at certain time intervals.
