Field anti-floating fortification water level determination method based on Mann-Kendall trend analysis
The invention provides a field anti-floating fortification water level determination method based on Mann-Kendall trend analysis, and belongs to the field of geotechnical engineering. The field anti-floating fortification water level determination method comprises the following steps of S1, collecting and arranging long-term water level observation data; S2, defining a Mann-Kendall trend test statistic S; S3, calculating a value Z of a Mann-Kendall trend analysis statistical variable; and S4, judging the range of the value Z, and determining an anti-floating fortification water level. By meansof the field anti-floating fortification water level determination method, the most reasonable anti-floating fortification water level is determined; and the problems that the historical highest water level is directly taken as the site anti-floating fortification water level in parts of projects in China at present, so that building base water pressure estimation is too high, and waste are caused is solved.
本发明提供了基于Mann‑Kendall趋势分析的场地抗浮设防水位确定方法，属于岩土工程领域，包括以下步骤，S1、长期水位观测资料收集整理；S2、定义Mann‑Kendall趋势检验统计量S；S3、计算Mann‑Kendall趋势分析统计变量Z值；S4、判定Z值的范围，确定抗浮设防水位。本发明确定最合理的抗浮设防水位；解决当前国内部分工程中直接拿历史最高水位作为场地抗浮设防水位，从而对建筑物基底水压力估计过高、造成浪费的问题。
