随着世界各国,尤其我国的城市化进程的不断加快,城市规模不断扩大,城市中高层建筑的密度越来越高,城市热岛效应(UHIE)及其带来的各类环境问题日益突出。对于城市热岛效应的研究目前主要集中在城市范围内的大气部分,对于它对城市赖于存在的地质环境的影响研究很少,而对土的工程性质的影响及其灾害效应常被忽视。从UHIE与城市地下土体工程性质间的关系出发,介绍了UHIE的成因和发展程度,剖析了城市环境中的土体与自然环境中土体的差别以及UH-IE影响土体工程性质的方式,初步分析了UHIE对土的工程性质的影响及其引起的灾害效应。分析成果对于开展城市热岛效应环境中土的工程性质变化及其灾害效应研究有重要的指导意义。
The urban heat island effect (UHIE) on soil engineering properties and the related disaster effect were usually ignored in the past. Based on the characteristics of UHIE and the environmental conditions of urban soil, the UHIE on soil engineering properties and the related disaster effect are preliminarily analyzed. The research results have great significance for further analysis on soil engineering properties in UHIE environment and their disaster effect.
