Pile and pile foundation engineering

The application and the design calculation methods of composite foundation with gravel pile and CFG pile based on engineering practice are analyzed, and the rational calculation methods are presented.

结合具体工程实例，对碎石桩- CFG桩组合型复合地基的应用和设计计算方法进行了分析，提出了合理的计算方法。

The jacked pile, as one of the types of pile foundation engineering, overcomes the resistance of soil and sinks to the preset level by less static pressure while affording a larger bearing capacity.

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。

By using a complete engineering example, this paper gives the data of static load test and the data of settlement observation of treated single pile and single pile complex foundation respectively.

文章介绍了一个完整的工程实例，并给出了处理后的单桩和单桩复合地基静载荷试验数据和沉降观测数据。
