| 摘 要： | 座落在岛状融区中的青藏高原沱沱河兵站楼房,由于跨年度施工,楼房各部位季节冻深和融化速度不一,引起不均匀下沉,致使墙体产生严重裂缝。岛状融区是工程地质环境敏感区。在太阳辐射强烈的青藏高原,现行建筑规范中房屋采暖对冻深的影响系数偏小,建议对北外墙中段和角端应比规范规定系数分别增大0.2和0.3。

| Abstract: | The Tuotuo River Army Service Station is located in island taliks of permafrost on the Qinghai-Xizang (Tibet) Plateau. Overyear construction results in different rates of freezing and thawing, causing differential subsidence and cracking. The island talik is a sensitine area in engineering geology. Because of the intense solar radiation on the Qinghai-Xizang Plateau, the coefficient of the effect of building heating on freezing depth, as regulated by the existing construction norm, is too small. Therefore, it is recommended that this coefficient should be increased by 0.2 and 0.3 for the middle part of northern wall and the corner walls, respectively. |
