摘要
首先对嵌岩灌注桩的承载机理进行了简要分析,提出应以变形和承载力作为双重控制指标进行该种桩型的设计和计算;其次对于强、中风化程度软质岩系的岩土工程勘察若干问题进行了讨论,结合地区经验给出了一些经验关系供参考;同时文中还介绍了一些工程计算实例.
At first, the bearing mechanism of cast-in-place piles embedded rock is briefly analysesed. The author consider that the design and calculation of this kind of piles should base on bearing capacity and settlement. Some geotechnical engineering investigation problems about highly-middle weathered soft rock are discussed and some local experience formulas are given about which normal value of the bearing capacity (fk), modulus of compressibility (E0), normal value of side friction (qs) and normal value of end bearing (qp). At the same time, some project examples are introduced.
