兰州安宁区滨河北路西段工程地质特性及地基基础建议

兰州市位于甘肃省中部,属中温带干旱和半干旱气候区,干燥少雨,四季分明,昼夜温差很大。研究地段位于黄河上游的兰州安宁区滨河北路西段黄河北岸Ⅰ级阶地,在黄河安宁区段具有代表性。本文通过作者多年在该区不同地段积累的工程地质勘察实际资料,结合地貌和沉积特征,从地层空间分布、物理力学性质等方面系统分析评价了岩土工程地质特性,选择了区内建筑持力层、提出了地基基础类型方案和建议,为该地段开发和建筑设计提供参考。

Engineering Geological Characteristics and Foundation Proposals in Western Section of Riverside North Road,Anning District,Lanzhou

Lanzhou City is located in the middle of Gansu Province which is in the temperate climate zone in arid and semi-arid,dry,dry,four seasons,a large temperature difference between day and night.Lot is located in the upper reaches of the Yellow River in Lanzhou,Anning District,Riverside north Road,north west of the Yellow River terraces Ⅰ,peace zone in the Yellow River representative.Through many years in the area of ？？the accumulation of different sections of the actual engineering geological survey data,combined with geomorphological and sedimentary characteristics,from the formation spatial distribution,physical and mechanical properties evaluation of systems analysis and other aspects of geotechnical engineering geological properties,select the region bearing construction layer,the proposed foundation type programs and proposals for the Lot reference for the design development and construction.
