摘要

针对淤泥堆场利用淤泥固化技术制作的人工硬壳层（MMC）地基的极限承载力问题，利用模型试验研究了人工硬壳层的无侧限抗压强度、厚度以及淤泥的不排水强度对这种人工硬壳层地基极限承载力的影响规律。结果表明，淤泥上覆人工硬壳层地基的极限承载力随人工硬壳层的无侧限抗压强度的增加呈指数增加的趋势，随硬壳层厚度的增加呈现出线性增加的趋势。

Abstract

For the bearing capacity problems of man-made crust (MMC) with solidified dredged sediment over dredged wastes dump sites

the effects of the MMC unconfined compressive strength

MMC thickness and sediment undrained shear strength to the ultimate bearing capacity of the MMC over dredged wastes dump sites were studied with model test. Test results show that the ultimate bearing capacity increases exponentially with the increase of MMC unconfined compressive strength

and increases linearly with the increase of MMC thickness.
