The landscape ecological construction is to protect biological diversity positively, which follows the theories such as adapting to nature, mutualism and symbiosis, adjusting structure and improving function, controlling parts and adjusting the whole, and other theories of landscape ecology. This paper took humid temperate zones, landscape ecozones etc. as examples to express how to use these theories to carry out landscape ecological construction. The author put forth three points of land ecological construction: protection of rare and endangered organisms; restoration and reconstruction of important ecosystems; protection of community diversity of plant.展开更多

Two alternative solutions for the pier cap on one of the bridge crossings over IH-35E in the IH-635 project were analyzed in this case study, a cast-in-place post-tensioned concrete cap and an innovative prefabricated steel-concrete com- posite cap. The approach was to use an estimation of direct costs for material and labor and consideration of con- struction time schedules. A supplementary numerical modeling confirmed that both alternatives behave elasti- cally under imposed loads. The direct cost of material and labor for the two alternatives were close. However, the composite alternative required 13 days less construction time, resulting in substantial cost savings from traffic closing in the very busy traffic corridor. Traffic closing costs were substantially higher than the direct costs, especially for the post-tensioned cap. The quantification of the benefits allows more confidence in the utilization of the composites caps, leading to faster completion of bridge projects and substantial economic savings.展开更多
