2007年以来,丽水市国土资源局一方面加强与市发改委、农办、扶贫办等部门的协调,积极做好项目包装工作;另一方面加强与省国土厅的沟通汇报,积极争取省国土厅对我市建设用地指标的支持,取得了明显成效,为保障全市经济社会发展对用地的合理需求作出了重要贡献。截至11月底,我市共争取到省国土厅追加我市各类用地指标7362亩,其中追加我市建设用地计划指标2082亩(其中市区1653亩,龙泉市354亩,缙云县75亩);标准农田建设奖励指标1037亩;2007年统筹奖励指标1705亩; 相似文献

Study on Failure Mechanism and Bearing Capacity of Three-Dimensional Rectangular Footing Subjected to Combined Loading 总被引:2,自引:0,他引:2
This paper presents two kinematic failure mechanisms of threc-dimensional rectangular footing resting on homogeneous undrained clay foundation under uniaxial vertical loading and uniaxial moment loading. The failure mechanism under vertical loading comprises a plane strain Prandti-type mechanism over the central part of the longer side, and the size of the mechanism gradually reduces at the ends of the longer side and over the shorter side as the corner of rectangular footing is being approached where the direction of soil motion remains normal to each corresponding side respectively. The failure mechanism under moment loading comprises a plane strain scoop sliding mechanism over the central part of the longer side, and the radius of scoop sliding mechanism increases linearly at the ends of the longer side. On the basis of the kinematic failure mechanisms mentioned above, the vertical ultimate bearing capacity and the ultimate bearing capacity against moment or moment ultimate bearing capacity are obtained by use of upper bound limit analysis theory. At the same time, numerical analysis results, Skempton' s results and Salgado et al. 's results are compared with this upper bound solution. It shows that the presented failure mechanisms and plastic limit analysis predictions are validated. In order to investigate the behaviors of undrained clay foundation beneath the rectangular footing subjected to the combined loadings, numerical analysis is adopted by virtue of the general-purpose FEM software ABAQUS, where the clay is assumed to obey the Mohr-Coulomb yielding criterion. The failure envelope and the ultimate bearing capacity are achieved by the numerical analysis results with the varying aspect ratios from length L to breadth B of the rectangular footing. The failure mechanisms of rectangular footing which are subjected to the combined vertical loading V and horizontal loading H (Vertical loading V and moment loading M, and horizontal loading H and moment loading M respectively are observed in the finite e 相似文献

本文采用生命周期评价(LCA)的方法,从原料获取、原料运输、产品生产、产品使用和最终处置五个阶段对可降解聚乳酸(PLA)包装塑料的能耗和环境影响进行了评价和量化。并选择7个影响类别进行影响分析:非生物耗竭潜力(ADP)、全球变暖潜力(GWP)、酸化潜力(AP)、富营养化潜力(EP)、光化学臭氧形成潜力(POCP)、人类毒性潜力(HTP)和陆地生态毒性潜力(TETP)。通过对生命周期评价结果的讨论,发现对环境影响最大的是产品生产环节。同时,在整个生命周期中,环境影响排名前三的类别分别为GWP、ADP和HTP,分别占32.63%、24.83%和14.01%。根据LCA的研究结果,减少环境影响的途径有:降低电耗、增加新能源的投入、提高生产过程中物料的转化率、使用有机和水溶性肥料代替传统肥料、使用环保型燃料建立完善的回收体系。 相似文献
