随着城市地下空间开发规模不断增大,城市地下空间开发的主要矛盾从基坑自身稳定问题逐渐转向基坑周边环境变形控制问题。周边环境复杂情况下的地下空间开发极易引起地表不均匀沉降,建筑物开裂,造成巨大的经济损失。因此需要系统性地研究城市各类明挖基坑开发形式所带来的环境影响及环境效应控制技术。本文介绍和回顾了统计经验法、数值模拟法、模型试验法在明挖基坑引起的环境效应研究中取得的研究成果,总结了各类研究方法及成果的优势和不足。介绍了现有环境控制技术及应用案例,总结了地下空间开发环境效应研究成果,并对今后研究方向提出了建议。

泰州大桥采用主跨为1 080 m三塔两跨悬索桥,中塔位于主江中心。通过对沉井基础和高桩承台钻孔桩基础等多项基础方案的比选,考虑到沉井结构受力明确、刚度大、工序简单,经济性高等优点,中塔基础最终选用沉井基础。根据塔柱底的构造要求,受力要求,沉井采用58 m×44 m四角倒圆的矩形沉井,沉井总高76 m。为了能在深水中顺利施工,沉井下部为钢壳混凝土结构,上部为钢筋混凝土结构。文中介绍了泰州大桥水中沉井的结构构造、施工方法、方案比较以及沉井的设计特点,可为今后类似工程起到很好的借鉴作用。

During August 1953 three strong earthquakes of magnitude ranging from 6.3 to 7.2 shook the Ionian Island of Cephalonia (Kefalonia), Greece, and destroyed almost the entire building stock of the Island which consisted primarily of traditional unreinforced masonry (URM) houses. The authorities went on to restructuring of the building stock, using a structural system that is most like what is known today as confined masonry. They designed about 14 types of one- to two-storey buildings providing the engineers with detailed construction plans. These buildings are known as “Arogi” buildings (Arogi in Greek meaning Aid). On the 24th of January and 3rd of February 2014, two earthquakes of magnitude 6.1 and 6.0 struck the island, causing significant soil damages, developing excessively high ground accelerations. Surprisingly, no damage was reported in the “Arogi” buildings. The seismic behavior of the buildings is examined by FEM linear analysis and it is compared to that of URM structures. Computed results illustrate that the displacements of identical URM buildings would be about twice the magnitudes observed in the corresponding “Arogi” ones, with the implication that the earthquake sequence of 2014 would have caused critical damage should the type of structure be of the URM type. Furthermore, it is illustrated that this low cost alternative method of construction is a very effective means of producing earthquake resilient structures, whereas further reduction of seismic displacement may be achieved in the order of 50% with commensurate effects on damage potential, when reinforced slabs are used to replace the timber roofs.
