摘要
强风化岩的力学指标不会随时间而增长，而淤泥层的固结，在端承桩条件下只能引起桩侧负摩擦而使桩的有效承载力略为下降。“解析法推算”所得桩极限荷载，只是预测试桩当时可能达到的极限荷载，而与“时间推移”无关。
The mechanical performance of the badly efflorescent rock would no increase by time, however with the sludge solidification, the pile available bearing capacity would reduce somewhat because of the negative friction on the side in the case of end borne. The ultimate bearing capacity calculated by 'the analysis method' is only the predication of the possible value at the time of pile being test, which has nothing to do with the 'time elapsing'.
