The usual travel time tomography method is based on geometrical ray theory,however,it assumes that the seismic wave has very high frequency,which often makes the tomographic inversion have ill posed problem because of the sparse ray distribution in the model space and finally affects the reliability and resolution of the tomographic results.

基于几何射线理论的旅行时层析方法假设地震波频率足够高，这样往往由于射线存模型空间的稀疏分布，使层析反演问题具有严重的不适定性，从而极大地影响层析成像结果的可靠性和分辨率。

The current research points out that for the CFCHS joints the linear extrapolation method can be used for chords,whereas the quadratic extrapolation method must be used for braces.The hot spot stress distributions on the CFCHS joints tend to be more uniform and their SCFs become smaller significantly,compared with the CHS joints.Axial tension on the brace puts the CFCHS joints at a disadvantage,which produces higher SCFs than axial compression.The effects of nondimensional geometric parameters β,τ and γ on SCFs of the chords of the CFCHS joints are basically the same as those of the CHS joints,but for the braces,there is a bit difference in the effects of parameters β,τ and γ between the two kinds of joints.Concrete has the function of improving the CFCHS joint rigidity and then decreasing SCFs which is expected to increase fatigue strength,but concrete strength grade does not exert significant influence on SCFs.

研究表明：CFCHS节点的热点应力，对主管可采用线性外推方法，对支管需采用二次外推方法；相比CHS节点，CFCHS节点的热点应力分布趋于均匀，SCF显著减小；CFCHS节点支管轴向受拉比受压不利，SCF增大；CFCHS节点几何参数β，τ，γ对主管SCF的影响效应与CHS节点基本一致，但是对支管SCF的影响效应与CHS节点有些差异；混凝土的作用主要是改善CFCHS节点刚度，从而降低SCF，并预期可提高疲劳强度，但混凝土自身强度等级的高低没有显著影响节点的SCF。

Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。
