Fault-plane solutions of the mainshock and 17 large aftershocks are computed on the DJS-6 computer from the data of the first motions of P waves. Based on the model of finite moving source, the fracture processes and the source parameters of the mainshock and three largest aftershocks are estimated.

Fault-plane solutions of the mainshock and 17 large aftershocks are computed on the DJS-6 computer from the data of the first motions of P waves. Based on the model of finite moving source, the fracture processes and the source parameters of the mainshock and three largest aftershocks are estimated. The Mainshock occurred on a nearly vertical right-lateral strike-slip fault, striking N 30°E, with an asymmetric bilateral fracture which propagated 70 km northeastward and 45 km southwestward with an average velocity of 2.7 km/sec. Source parameters of the mainshock such as the average dislocation, seismic moment and stress-drop are estimated to be 136 cm, 1.24×1027 dyne, cm and 12 bars respectively.Most of the aftershocks with ML > 5.0 occurred near the main fault plane and along the fracture branches at both of its ends. These fracture branches are located in the dilatational quarters and make about 80° angles with the mam fault plane. On the two fracture branches, most of the major aftershocks are concentrated. A mechanical analysis of this phenomenon of fracture propagation is attempted in this paper.It is shown that for complex deformations, the fracture propagation no longer takes place along the original plane for brittle materials but deviates from it by a certain angle. The mechanical model used to calculate this deviation angle of fault yields results which agree essentially with the observation.Based on the above results, it can be inferred that the characteristics and mechanical conditions of the Tangshan earthquake as well as those of the Haicheng earthquake are quite different from those of the earthquakes occurring on some great faults which may be explained by stick-slip mechanisms. These two earthquakes are not only caused by the horizontal stress fields but also by local vertical forces induced from the movement of the underground materials. It is also worthy of note that Tangshan earthquake is different from Haicheng earthquake in that it occurs in a relatively homogeneous and brittle medium and therefore no foreshocks took place before the mainshock.

由 P 波初动符号资料在 DJS-6机上计算了主震及17个较大余震的断层面解,并按照有限移动源模式测定了主震及三个最大余震的震源参数.主震是发生在一个近似直立的右旋走滑断层上,走向 N30°E,破裂方式为不对称的双侧破裂,以2.7公里/秒的平均速度向北东传播70公里,向南西传播45公里.测定的主震震源参数例如平均位错136厘米,地震矩1.24×10~(27)达因·厘米,应力降12巴等.大多数 M_L>5.0的余震是发生在主破裂面附近及主破裂面两端的扩展分支上,该扩展分支位于膨胀符号区并与主破裂偏离80°左右.较大余震的多数亦集中在这两个扩展分支上.本文试图从理论上分析这种断裂扩展的力学特征.对于脆性材料的复合变形情形,破裂不再沿原来平面扩展,而是与原来平面偏离一个角度的另一面内扩展.并提出一个力学模型,计算了断层扩展角,计算结果与观测事实比较吻合.根据以上结果,本文讨论了唐山地震特点及发生的力学条件,认为唐山地震不同于发生在大断层上能用粘滑机制解释的那类地震,它和海城地震类似的是,除水平应力场作用外,还可能有地下物质的变迁,由于这种变迁使局部地壳受到垂直力.它和海城地震不同的是,它发生在一个比较均匀的脆性介质...

The fracture processes and focal parameters of the Tonghai earthquake (Ms=7.7) which occurred on January 5, 1970 are estimated from the data of the P waves.

The fracture processes and focal parameters of the Tonghai earthquake (Ms=7.7) which occurred on January 5, 1970 are estimated from the data of the P waves. This earthquake occurred on the Qujiang (#) fault striking NWW and propagated nearly, along it with an asymmetric bilateral fracture which propagated 26 km northwestward and 40 km southeastward with an average velocity of 2.3 km/sec. Estimation of the seismic moment of this earthquake by spectral analysis gives a value of 4.34#1026 dyne-cm. This value is considerably lower than that given by geodetic data. This difference indicates that some aseismic slips had taken place on the fault before and after Tonghai earthquake.As in Tangshan (#) earthquake, most of the aftershocks of this earthquake occurred along the fracture branches at both ends of the main fault. On the other hand, the fracture branch on the southeast end is noticeable for Tonghai earthquake. This fracture branch is located in the dilatational quarters and makes an angle of about 80 with the main fault.

本文根据长周期地震仪记录的P波资料,研究了通海地震(M_s=7.7)的震源参数和破裂过程。该地震沿着北西西走向的曲江断裂扩展,为非对称的双侧破裂,北西侧为24公里,东南侧为32公里,平均破裂速度为2.3公里/秒;地震矩为4.34×10~(26)达因·厘米,应力降为21巴;地震前后存在无震滑动;余震除沿主破裂面分布外,还大量集中于主破裂面的东南端的扩展分支上,并与主破裂面偏离80°左右。

From January 1985 to April 1994,we treated 328 cases of open tibiofibular fracture by primary internal fixation of rectangle shape intramedullary nails. Of them, 18 had bilateral fractures. An average time of follow -up was 56 months. The excellent and good rate was 94.1%. The authors conclude that because the operation has little trauma,retained better blood supply of bone stump and solid internal fixation, it is a better method to treat open tibiofibular fracture.

自1985年1月至1994年4月我们用矩形髓内钉一期内固定治疗开放性胫腓骨骨折328例(其中18例为双侧,共346侧),平均随访56个月,结果优良率为94.1%。作者认为,本法手术创伤小,能最大限度保留骨折端血供,内固定牢靠,不失为处理开放性胫腓骨骨折的一个较好的内固定方法。
