随着沿海滩涂的开发，许多围海造陆工程需要在淤泥质软土区抛石挤淤形成围堰，且抛石斜坡堤下淤泥质软土的孔隙水压力测试有着广泛的应用。孔隙水压力测试对软弱土层的固结、有效应力的增加情况以及抛石斜坡堤的稳定也有着重要的意义。本文对抛石挤淤形成的斜坡堤下淤泥质软土中的孔隙水压力测试应用进行了研究，并积累经验，可以为堆载预压工程或类似的工程提供参考。
隨著沿海灘塗的開髮，許多圍海造陸工程需要在淤泥質軟土區拋石擠淤形成圍堰，且拋石斜坡隄下淤泥質軟土的孔隙水壓力測試有著廣汎的應用。孔隙水壓力測試對軟弱土層的固結、有效應力的增加情況以及拋石斜坡隄的穩定也有著重要的意義。本文對拋石擠淤形成的斜坡隄下淤泥質軟土中的孔隙水壓力測試應用進行瞭研究，併積纍經驗，可以為堆載預壓工程或類似的工程提供參攷。

With the development of coastal shoal,oozing soft soil areas are treated to form cofferdams by using riprap silt-extrusion method in many sea reclamation projects. And pore water pressure test of oozing soft soil under riprap sloping dyke is widely applied in engineering. The test results play an important role in monitoring the consolidation of soft soil layer,the increase of effective stress and the stability of riprap sloping dyke. Research is carried out for the application of pore water pressure test to oozing soft soil under sloping dyke which is formed by using riprap silt-extrusion method. And experiences are accumulated,which will provide references for surcharge preloading construction or similar projects.
