Quantitative Tectonic Markers of Large Coastal Earthquakes in Fujian, Guangdong, Taiwan and Hainan——with a Discussion of Qualitative Indicators

This paper expounds the quantitative tectonic indicators and some qualitative indicators of large earthquakes in the coast areas of Fujian, Guangdong, Taiwan and Hainan. The main quantitative indicators include uplift amplitude of the Moho, Quaternary and Late Holocene coasts. The paper also gives a brief account of the research method on quantitative indicators of surface uplifted zones. Taiwan is a famous neotectonic zone and an area of large earthquakes in the world. There is only one large-earthquake area in each of Fujian, Guangdong and Hainan Provinces. Along the coast large earthquake areas there are certainly many remains of crustal activity. Among these remains, coast activity, taking the sea level as the accurate marker horizon, can determine not only the amplitude of coastal elevation and subsidence in a certain period, but also the cycle and rate of positive or negative movements.     

联合古陆演化周期中超大型含煤及含油气盆地的形成

联合古陆———Ｐａｎｇｅａ的拼合与裂解反映了地球系统内部的巨大变革，这一过程根本上改变了浅部圈层的构造和环境。地史上超大型含煤盆地及含油气盆地与Ｐａｎｇｅａ的演化周期密切相关。在石炭纪及二叠纪拼合过程中形成了一系列超大型聚煤盆地；晚侏罗世Ｐａｎｇｅａ开始裂解，出现全球性裂陷作用期，大西洋张开，许多与裂陷有关的大型叠合盆地形成。在这些盆地中已发现十余个与晚侏罗世烃源岩有关的巨型含油气系统。上述情况表明Ｐａｎｇｅａ演化过程中出现了对能源资源聚集极为有利的古构造、古环境和古气候条件。

CHARACTERIZATION AND FORMATION MECHANISM OF THE CENTRAL UPLIFT OF THE QIANGTANG BASIN

The Qiangtang basin is located between Kekexili-Jingshajiang suture belt and Bangong-Lujiang suture belt, and is divided into the north part and south part by the central uplift that has no crop out of Mesozoic strata. When the Jinshajiang Ocean was closed, the subducting plate was subducted southward. In the central part of the Qiangtang basin, the cushioning effect of the asthenosphere resulted in the thermal doming of the mantle and subsequent large-scale anatexis. Mantle source materials and antectic materials were upwelled and extruded into the middle crust, leading to the thickening of the middle crust and the heating and weakening of the middle to upper crust, and resulting in the rapid deformation (detachment) and tectonic erosion, and in the isostatic uplifting and the formation of metamorphic core complex. The upwelling of anatectic materials would further enhance the buoyant repercussion, which would combine with the side stress due from extrusion in resulting in the formation of an extension     

关于地基承载力的探讨

以土质地基为研究对象 ,结合载荷试验 p s曲线 ,应用土体的极限平衡理论 ,对地基土的变形性状、地基土承载力以及承载力修正等问题进行了分析。分析结果显示 :地基土承载力不单是地基土抗剪强度指标的函数 ,同时还与作用其上的基础埋深及基础宽度等因素密切相关。进行地基基础设计时 ,应根据实际的基础埋深与宽度对勘察资料中的地基土承载力进行修正 ,并提出了有关承载力修正的建议

A new method for testing pile by sin- gle-impact energy and P-S curve

Introduction Through many year's practices by vast numbers of scientific and technological workers andefforts from all aspects, the dynamic testing method of high-low strain has formally entered intothe technical code of foundation pile test of construction at last (The Industry Standards of thePeople's Republic of China, 2003). The striking mode of the dynamic testing method of high strainis stipulated as hammer in the code, the striking of rocket can also be used. The latter is widely…     

载荷试验确定基床系数修正方法的讨论

Winkler地基模型是目前工程界应用最广的一种地基模型，但对其关键参数——基床系数k的确定，许多文献的表述并不一致。该文在大量试验资料的基础上，通过对该问题的深入研究，阐明了通过载荷试验确定基床系数修正方法的有关概念。对于砂性土地基，载荷板试验得出的基准基床系数仅需要进行基础大小修正，而对于粘性土地基，则需要进行基础大小和基础形状两项修正。
