     AS M interface is in stable, so it is not eroded by deep materials, while C interface is crooked at the block edge of Hengyang, but it is not buried in deepth and its confining pressure is in low state. Therefore we think that it is difficult to accumulate enough strain energy that need to start a strong motion earthquake.
     由于M界面平稳,未受深层物质侵蚀以及C界面虽在衡阳地块边缘出现挠曲,但其埋藏较浅,围压低,因此认为该区难以积累足以发动强烈地震所需的应变能。

From the results of [1] a set of theoretical curves used to determine the Q-value by means of the amplitudes of first P arrivals recorded at many stations are obtained in this paper. A portion of the aftershock data of the Haicheng earthquake of 1975 has been employed to determine the Q-value of the upper crust of the Haicheng region. Comparison with the QM-value of the top part of the upper mantle in this area obtained by the first Pn amplitudes data recorded at stations on the Liaodong Peninsula from some...

From the results of [1] a set of theoretical curves used to determine the Q-value by means of the amplitudes of first P arrivals recorded at many stations are obtained in this paper. A portion of the aftershock data of the Haicheng earthquake of 1975 has been employed to determine the Q-value of the upper crust of the Haicheng region. Comparison with the QM-value of the top part of the upper mantle in this area obtained by the first Pn amplitudes data recorded at stations on the Liaodong Peninsula from some aftershocks of the 1976 Tangshan Earthquake sequence as well as some statistical results for the first half period of P and Pn suggest that there exist a difference in attenuation of the top part of the upper mantle between the southeastern portion of the Haicheng Earthquake region and other regions. This may imply that the deep materials there are melted in higher degree than in other parts of the area.

本文用文献[1]的结果计算了可以用多台(?)初动振幅测定 Q 值的理论曲线,并使用海城地震的部分余震的资料测定了海城地区地壳上层介质的 Q 值.通过与由 P_n 资料得到的上地幔顶部介质的 Q_M 值比较,并对 P_(?)、(?)初动半周期进行统计表明,海城地震区东南部上地幔顶部介质的衰减特征与其他地区的不大相同,与地壳上部介质的衰减特征也不一样,说明那里深部物质的熔化程度可能比其他地方的物质的熔化程度高.

The main purpose of this paper is to study the mediumterm precursory mechanism of the 1976 Tangshan earthquake. We use 2-D nonlinear finite element model, to simulate the structure of the profile across Tangshan region, to analyse the relationship between the nonhomogeneousity of profile structure and the stress concentration in the source region, between the rock dilatation and the ground -uplifting, and other anomalies before the event. It is shown that if there is a solid body under the ground surface for...

The main purpose of this paper is to study the mediumterm precursory mechanism of the 1976 Tangshan earthquake. We use 2-D nonlinear finite element model, to simulate the structure of the profile across Tangshan region, to analyse the relationship between the nonhomogeneousity of profile structure and the stress concentration in the source region, between the rock dilatation and the ground -uplifting, and other anomalies before the event. It is shown that if there is a solid body under the ground surface for a few or more than 10km in the source region, the rock-dilating is possible. It makes the ground upheaval, and causes seismicity and wave velocity anomaly, deep material up-welling. So the rock-dilatation may be the basic medium-term precursory mechanism of the 1976 Tangshan earthquake.

本文主要目的在于研究唐山地震中期前兆的形成机制。采用二维非线性有限元模型,对穿过唐山的剖面结构进行模拟计算,研究剖面结构的不均匀性与震源区内应力集中的关系,岩石膨胀与地面隆起,以及其他震前异常的关系。研究结果表明,在震源体内存在坚固体的条件下,在地下几公里至十几公里处发生岩石膨胀是可能的,由此在地面造成隆起,并为地震活动异常,波速异常,深部物质上涌提供条件,故岩石膨胀可能是唐山地震中期前兆的基本机制。
