某电厂基础施工后由于停工时间较长，基础底面下的地基土经过应力释放、雨水浸泡等过程，其力学性能会发生一定程度的变化，为检测基础下地基土承载力变化情况，运用了钻探、标准贯入试验、静力触探和土工试验等方法进行综合检测。通过对同一基础承台内与承台外试验测试数据统计对比，以及现阶段地基每个检测单元与施工图原位测试数据统计对比分析，得出场地复工前后地基承载力的变化。
某電廠基礎施工後由于停工時間較長，基礎底麵下的地基土經過應力釋放、雨水浸泡等過程，其力學性能會髮生一定程度的變化，為檢測基礎下地基土承載力變化情況，運用瞭鑽探、標準貫入試驗、靜力觸探和土工試驗等方法進行綜閤檢測。通過對同一基礎承檯內與承檯外試驗測試數據統計對比，以及現階段地基每箇檢測單元與施工圖原位測試數據統計對比分析，得齣場地複工前後地基承載力的變化。

a power plant foundation construction after due to downtime is longer, the bottom of foundation foundation soil after stress release, the rain soaked process, its mechanical properties will change to a certain extent, for the detection of foundation bearing capacity of foundation soil under thechanging situation, the use of drilling, comprehensive detection of standardpenetration test, static cone penetration test and soil test method. Through the test on the same foundation platform inside and outside the cap test data statistical analysis and comparison, the present stage of the foundation of each detection unit and the construction drawing of in situ test data statistical comparison, playing to the resumption of work before and after the change ofbearing capacity of foundation.
