高桩码头施工时必须将大量长桩沉入土坡中,由于桩体的挤入,扰动破坏了土体结构,在土体内引起相当大的超静孔隙水压力,降低了土的强度,促使岸坡变形开裂甚至失稳,在以往工程中,不乏这样的先例。 为此,在上海某码头施工过程中,采用锤击沉桩和静压沉桩两种施工方式时实测土 During the construction of piled wharves, a large number of long piles must be sunk into the soil slopes. Due to the penetration of the piles, the soil structure is disturbed and disturbed, causing considerable excess pore water pressure in the soil, reducing the soil strength and promoting Deformation and cracking of bank slope or even instability, in the past projects, there is no shortage of such precedent. For this reason, during the construction of a wharf in Shanghai, the soil under test is measured by two methods of hammering pile sinking and static pressure sinking pile
