利用GPS、大地电磁、P波层析成像等数据分析了青藏高原东部地壳运动情况和中下地壳物质流的分布及运动情况,提出了青藏高原东部地壳物质流变模型,认为在青藏高原东部存在两条巨大的、具有固定通道和边界的弱物质流,其他区域则有离散的、不均匀的弱物质流分布。巴颜喀拉块体内部的弱物质流在向东流至龙门山断裂带时,大部分弱物质沿断裂带向南北方向分流,小部分弱物质在断裂带附近沉积、上涌,造成通道堵塞,最终引发了汶川地震。 Based on the data of GPS, magnetotelluric and P-wave tomography, the crustal movement and the distribution and movement of crustal material flow in the eastern Qinghai-Tibet Plateau are analyzed. The crustal material rheological model is proposed in the eastern Qinghai-Tibet Plateau. Two huge, weak material flows with fixed channels and boundaries, and other regions with discrete, inhomogeneous, weak material flow distributions. When the weak material flow in the Bayanhar block flows eastward to the Longmenshan fault zone, most of the weak materials divert north and south along the fault zone, and a small part of the weak material deposits near the fault zone, causing the channel to become blocked , Eventually triggered the Wenchuan earthquake.
