Non-diapiric, the overpressured top boundaries in the south and the margin of Yinggehai basin are often deep-buried, and are distinctly controlled by the formations and their lithologies.

在裂谷或裂陷盆地中，盆地形成的构造作用主要是拉张作用，由于岩石圈的拉薄而引起盆地的形成和沉降，盆地形成后盆地内沉积物和水的充填会引起岩石圈的均衡调整下降。

The main works of this paper are as follows.First, according to the three-step method, 1-D unsteady flow model in river network is introduced. A new topological structure is presented to describe and store the topology information and data in river network ,which realises the connection between GIS and the numerical program of hydraulic calculating and turns the program into a universal one .A new formula of internal boundary conditions with double-recursion algorithm is deduced, and the relationship of recursive coefficient between imaginary channel length and non-imaginary channel length is presented ,which makes sure that the model can comprise the numerical simulation of the internal boundaries such as side pipe outflow ,barrage, slice gate and drainage pump station.

主要工作如下：(1)根据三级解法建立了一维河网非恒定流模型，并提出了一种新的数据结构来描述和储存河网拓扑信息，方便了GIS平台和数值计算程序的衔接，实现了三级解法程序的通用性；从河段方程组出发，根据虚设河段法推导出了内边界条件的双追赶法公式，指明了虚设河段的追赶系数和非虚设河段追赶系数的关系，从而使模型可以模拟集中旁侧入流、堰、闸、水泵等内边界对行洪过程的影响。

Three-dimensional visco-elastic artificial boundaries in time domain are developed by means of theory of elastic wave motion in this paper.

应用弹性波动理论，发展了实现波动直接模拟的三维时域粘弹性人工边界。
