摘要
利用重型动力触探测试的原理,以西藏大学农牧学院职工周转房地基土为例进行了动力触探测试,测试结果表明:场地剖面上发育着三种河床冲积物,全场分布均匀。其中,卵石地基承载力高(fak=240kpa),是良好的基础持力层。为西藏林芝地区类似工程项目地基提供了参考依据。
the soil foundation of staff Housing in Institute of Agriculture and Animal Husbandry of Tibet University as an example, a dynamic penetration testing was made by using the principle of heavy dynamic penetration test. The results showed that three different alluvial sediments, with even distribution at whole site, developed at sections of the site and amongst the gravel foundation has highest capacity （fak=240kpa） and is a good foundation bearing stratum. This can provide a reference for the soil foundation of similar projects in Nyingehi.
