中文摘要 | 本文共探討了臺灣北部及東北角、宜蘭等共九個地點的砂土是否可以應用在工地密度試驗之砂錐法檢測中,以減少工地密度試驗之成本。經過試驗與比較,發現以AASHTO法檢核砂土的適用性時,除了淺水灣的原始砂與清洗砂不符合要求外,其餘砂土不論原始砂、清洗砂或單一篩號砂土皆能應用;但若以ASTM規範來檢核時,則只能以單一篩號(#60以上,#10以下)的砂土才能滿足要求;對於CNS標準而言,除了豆腐岬砂之外均符合適用條件。 |
英文摘要 | In standard test method for density and unit weight of soil in place by the sand-cone method requires standard sand as fill material, in this paper we obtained 9 littoral sand samples that took from north and northeast of Taiwan. By way of a series tests and comparison, only the Chian-Sui bay’s original and washed completely littoral sand can’t conforming to the AASHTO standards. But using the ASTM standards to check them, only the sands that retaining in a single sieve that between #10 and #60 in accordance with the ASTM standards, and 8 sands are in accordance with the CNS standards. |
