1 从灌注桩承载机理看质量监理的关键1.1 地基承载力的监理。从桩的施工程序来讲,在质量监理中,首先确保地基承载力符合设计要求,否则将使桩失效。地基承载力取决地质的构造强度。如果施工地区处于软弱带,在施工中就要注意夹层的存在,如漯河某厂化学处理房,某单位施工的钻孔端承摩擦桩21号桩,经抽芯检验,发现该桩的桩底坐 1 from the pile bearing mechanism to see the key to quality supervision 1.1 foundation bearing capacity supervision. From the pile construction process, quality supervision, first of all to ensure that the foundation bearing capacity meets the design requirements, otherwise it will make the pile failure. Foundation bearing capacity depends on the geological tectonic intensity. If the construction area in the weak zone, pay attention to the existence of mezzanine in the construction, such as a chemical treatment plant in Luohe, a construction unit of the boring end bearing friction pile 21, the core-pulling test found that the bottom of the pile sit
