抓住机遇 加快发展 把建行西藏区分行办成“好银行”

新世纪初,党中央作出实施西部大开战略的重大决策,西藏是国家在西部大开发中实行特殊扶持政策的重点地区。今年6月份,中共中央、国务院在北京召开了第四次西藏工作座谈会,会议提出了进一步做好新世纪初西藏发展、稳定工作的方针、政策和措施。建行西藏区分行如何抓住机遇,在积极支持西藏经济跨越式发展的过程中。

China’s Western Development Strategy for Modernization Drive

The Western Development Strategy(WDS)is a key aspect of China’s coordinated regional development strategy and effort to build a modern country.The world is undergoing profound changes that have not been witnessed in a century.This paper discusses the WDS’s importance in regards to China’s modernization drive and the great rejuvenation of the Chinese nation.First,this paper identifies the WDS’s mission to improve people’s livelihood in China’s western regions,promote common prosperity for the Eurasian continent,and support the green transition of China’s and Eurasian energy economic and environmental systems,and safeguard ecological security in Asia at large.Second,this paper suggests that the key to the WDS is to reshape the geographical layout of economic activity in the western regions to avoid inefficiency.Specifically,China should develop a compact geographical layout of economic activity in the western regions,introduce a unique competition strategy,as well as find solutions for coordinated regional development based on key river basins.Finally,develop smart internet and inland free ports within the western regions.

Influence of moisture content on shearing strength of unsaturated undisturbed quaternary system middle pleistocene

The unsaturated undisturbed quaternary system middle pleistocene loess,a typical unsaturated soil,often occurs in the implementation of western development strategy.To obtain the shearing strength characteristics of this unsaturated undisturbed loess,based on the analysis of mineral composition,the triaxial shear test of undisturbed quaternary system middle pleistocene loess under different moisture contents is conducted with the specialized triaxial instrument for unsaturated soil.The test results show that the mainly mineral composition of undisturbed quaternary system middle pleistocene loess is quartz and albite.Under the same confining pressure,the matric suction increases with the decrease of moisture content.The smaller the moisture content,the larger the matric suction;the higher the moisture content,the lower the matric suction.Under the same moisture content,the matric suction increases with the confining pressure and reaches a maximum when the confining pressure is 100 kPa,and then decreases with the increase of confining pressure.This phenomenon is closely related to the grain contact tightness of soil mass under high confining pressure.According to the triaxial test of loess,the sample of loess experiences 4 stages from loading to failure:1) compaction stage;2) compression stage;3) microcrack developing stage;4) shear failure stage.The test sample is of brittle failure(weak softening)under low moisture content and confining pressure.With the decrease of matric suction and the increase of consolidated confining pressure,the stress-strain curve changes from softening type to ideal plastic type.In the shearing strength parameters of unsaturated undisturbed loess,the influence of moisture content on internal friction angle is small,but that on cohesive force is obvious.Therefore,the shearing strength of unsaturated undisturbed loess is higher than that of saturated undisturbed loess and varies with the moisture content.
