摘要:
临江工程场地因其土层渗透性较强，且江水在汛期内水位变化加剧对场区内地下水带来很大影响，不宜直接采用地面高程或洪水位作为建筑抗浮水位。对此，以福州地区某一临江工程为例，提出根据规范法、基于地下水渗流理论的半经验公式法和数值模拟法来预测抗浮水位，3种方法得到的建议抗浮水位分别为10.00、9.78、9.08 m。并通过统计周边场地水位资料，发现勘察期间历史最高水位和洪水位高程普遍低于以上3 种方法的计算结果。验证了临江建筑抗浮水位直接采用地面高程或江水洪水位的不足和片面，为今后类似建设项目抗浮水位的选取和抗浮设计施工提供参考和依据。
Abstract:
Due to the strong permeability of the soil layer and the intensified water level change of the river water during the flood season, the underground water in the site is greatly affected. Therefore, the ground elevation or flood level should not be directly used as the anti-floating water level of the building. In this regard, with a riverside project in Fuzhou as an example, it was proposed to predict the anti-floating water level according to the standard method, the semi empirical formula method based on the groundwater seepage theory and the numerical simulation method. The recommended anti floating water levels obtained by the three methods are 10.00m, 9.78m and 9.08m respectively. Through the statistics of water level data of surrounding sites, it was found that the historical highest water level and flood level elevation during the survey were generally lower than the calculation results of the above three methods. The research verifies the inadequacy and one-sidedness of directly using the ground elevation or river flood level of riverside buildings, and provides reference and basis for the selection of safe anti-floating water level and anti-floating design and construction of similar construction projects in the future.
