摘要
对于发生在1995年1月17日日本国兵库县南部地震中,以神户市为中心的临海地域中大量由于液化土层的侧向流动引起护坝附近建筑物桩基础在地层中的典型破坏形式进行了破坏和应力分析。将震后破坏建筑物详细的地基调查报告以及用倾斜计及可视照相机等测量手段得到的桩基变形实测结果与解析结果进行了比较分析,对临海建筑物桩基础的破坏机制进行了研究,验证了应力解析的方法-荷载分布法的有效性和实用性。
The case studies on the damaged pile foundation caused by the lateral soil flow due to sand liquefaction during the 1995 Hyogoken-Nanbu earthquake are discussed in this paper. The distributed load method is utilized to simulate the effect of the lateral soil flow to pile foundation, and through the analysis result is compared with the site digging results in reports of the damaged buildings, the mechanism of the damaged pile modes is studied, and we have concluded that calculated stress and deformation of piles are good agreement with the actually observed one. Practicability and availability of the distributed load method are verified.
