压入式沉桩是以较小的静压力，使桩克服土体的阻力，把预制钢筋混凝土桩沉入预定的标高，从而获得较大的承载力的桩基工程。近年来，上海地区的压入式沉桩有较大的发展。压入式沉桩由于没有锤击式的锤击应力，因此桩的配筋及混凝土强度等级相对于打入式沉桩要求要低。本文通过工程实例，主要对压入式沉桩的承载力及桩基沉降等做了一些测试工作，对压入式沉桩的压桩阻力、特别是对压入式沉桩的最大深度及压载以及桩持力层等问题提出了新的建议和看法。
Push-in type sinking pile is a pile foundation project with smaller static pressure, so that the pile overcomes the resistance of soil and sinks prefabricated reinforced concrete piles into predetermined elevations to obtain larger bearing capacity. In recent years, the push-in piles in Shanghai have developed greatly. Push-in piles have no hammering-type hammering stress, so the reinforcement of the piles and the strength of the concrete are lower than those required for driven sinkers. In this paper, through the engineering example, some tests are performed on the bearing capacity of the push-in sinker and the settlement of the pile foundation. The resistance of the pile to the push-in sinker, especially the maximum depth and pressure of the push-in sinker Issues such as the carrying capacity and the bearing capacity of the pile put forward new suggestions and opinions.
