| 摘 要： | 分别按国外公式和上海公式对杭州地区土的静止侧压力系数K0用扁铲侧胀试验法进行了估算，分析后认为国外公式偏差较大，而上海公式在部分土体中也需要修正。对杭州地区38个试验孔4000多份数据进行了分析，认为土性的地区性差异是引起误差的主要原因。应用Mindlin解，考虑了土体材料指数ID的影响，探讨了杭州地区用扁铲侧胀试验资料估算静止侧压力系数‰的方法，并用杭州地铁一号线多个车站的实际工程资料进行了验证，结果令人满意。

| Abstract: | According to the formula used abroad and the formula used in Shanghai respectively,the lateral earth pressure coefficient at rest K_0 in Hangzhou by flat dilatometer tests is estimated.After the analysis,it is thought that there is the bigger deviation from the foreign formula,and the applicability of the formula in Shanghai also needs to be corrected for the use in some soil of Hangzhou.After the analysis on more than 4000 data from 38 examination boreholes in Hangzhou,it is shown that the local difference... |
