摘　　要：烟台市区周边基岩主要为元古界变质岩,尤其以片岩、片麻岩分布较为广泛。由于不同年代岩石风化程度差异性较大;同一风化程度情况下,地层天然承载力差别较大,因此提供该区域强风化片岩、片麻岩准确的天然地基承载力是岩土工程勘察的难点。本文以烟台高新区某建筑物为例,通过对天然地基浅层平板载荷试验与轻便动力触探试验对比,确定天然地基的承载力。The bedrock around Yantai urban area is mainly metamorphic rock formed in Proterozoic,especially schist and gneiss.Due to significant differences in weathering degree of rocks in different eras and the natural bearing capacity of the stratum varies greatly under the same weathering degree,so it is difficult for geotechnical investigation to provide accurate natural foundation bearing capacity in strongly weathered schist and gneiss in this area.This paper takes a building in Yantai High-Tech Zone as an example to determine the bearing capacity of natural foundations by comparing shallow plate load tests with portable dynamic penetration tests.
