In this paper, the roughly-cemented oil and gas-bearing sandstone is regarded as a viscous or viscoelastic fluid. A model of viscous (or vis-coelastic)fluid layer intercalated with elastic solids is set up. The reflection and transmission coefficients for simple harmonic plane SH wave on the fluid layer are determined. They are categorized to the function of frequency dependence,

This paper deals with an experiment on cylindrical marble samples in which artificial unlinked cracks making angles of about 30?with the cylindrical axis are cemented by epoxy resin. The effect of crack size and filling material on energy of shear fracture are studied experimentally. The results are that as the relative area of the cracks increases from zero to 90% the shear fracture energy decreases gradually from (6.9±2.1) ×103J/m2 to(0.6±0.5)×103J/m2. The theoretical values of stress drop obtained by...

This paper deals with an experiment on cylindrical marble samples in which artificial unlinked cracks making angles of about 30?with the cylindrical axis are cemented by epoxy resin. The effect of crack size and filling material on energy of shear fracture are studied experimentally. The results are that as the relative area of the cracks increases from zero to 90% the shear fracture energy decreases gradually from (6.9±2.1) ×103J/m2 to(0.6±0.5)×103J/m2. The theoretical values of stress drop obtained by Knopoff 's method and the method of slip-weakening model are almost the same. However, the ratio of these values of stress drop to that observed experimentally increases gradually and reaches about 10 as the relative crack area increases from zero to 90%. At the same time, some possible factors causing the large difference of stress drop during earthquakes and rock failure and the large difference of values of shear fracture energy obtained by various methods, are discussed. It has been proposed that the effect of the honeycomb-contact structure of fault surfaces may be important.

采用大理岩圆柱试样,与轴线约成30°角预制不连续裂缝,再用环氧树脂胶接,以实验观测裂缝尺度及其填充物对剪切破裂能的影响.结果表明:当裂缝相对面积从0增加到90%时,破裂能从(6.9±2.1)×10~3焦耳/米~2逐步降到(0.6±0.5)×1O~3焦耳/米~2;而使用 Knopoff方法和引入滑动弱化模式后的方法,求得的理论应力降几乎不变.它们与实测应力降的比却逐步增大并达到10.同时,分析了地震时和岩石破裂时的应力降差别很大,以及不同方法所得破裂能差别很大的原因,认为断层的蜂窝状接触对上述问题可能有重要影响.

In the coastal area of Southern Fujian,the late Pleistocene sediments have a wide distribution (Fig.1).The late Pleistocene strata are mainly composed of following sediments in ascending order:Dgrey medium-fine sand,2)black mud or peat,and 3)yellow sand and sandy clay.The other possible late Pleistocene deposits,so-called "Old Red Sand",are the semi-cemented,well-sorted,and red quartz silt-fine sand.These deposits are distributed over the bays and gullies of mainland and the islands,and constitute the...

In the coastal area of Southern Fujian,the late Pleistocene sediments have a wide distribution (Fig.1).The late Pleistocene strata are mainly composed of following sediments in ascending order:Dgrey medium-fine sand,2)black mud or peat,and 3)yellow sand and sandy clay.The other possible late Pleistocene deposits,so-called "Old Red Sand",are the semi-cemented,well-sorted,and red quartz silt-fine sand.These deposits are distributed over the bays and gullies of mainland and the islands,and constitute the second terrace,tiebar and other littoral accumulation landforms.In this paper,a number of natural outcrop sections of late Pleistocene strata have been described and drown in Fig.2.Based on the sedimentologic and geomorphologic investigation in the field and the data of 14C dating (Table 1),analyses of foraminifers and ostracods (Table 2) and pollen analysis (Table 3),the following conclusions can be obtained:1.The grey and yellow sand and sandy clay intercalated with black mud or peat belong to the late Late Pleistocene,i.e.the middle and late pleni-glacial substages of the last Glacial Stage,between about 40,000 and 16,000 years B.P..2.The grey and yellow sand and sandy clay,especially the black mud or peat,of the late Late Pleistocene are mainly the deposits of marine-land transitional facies,in part the littoral,and in part lake and swamp facies.3.On the whole,the climate of the late Late Pleistocene was warm and humid,but sometime cooler and drier.4.The "Old Red Sand" is the littoral sediments which were deposited under the heat and humid climate.It might be deposited during the late stage of Late Pleistocene,but the possibility of forming in the earlier period can not be ruled out.
