1985年我队受温州市海洋渔业公司的委托，承担了该公司理鱼车间钻孔桩基础的施工任务。该理鱼车间紧靠瓯江边而建，其基础原拟采用强夯法改善地层的承载能力。但经工程勘察后得知，下伏基岩由南西向北东倾斜达30′，因此担心车间建成后，在重载有下车间会沿基岩表面产生滑波现象，从而将强夯加固地基的方法，改为钻孔灌注桩基础。柱的类型选用嵌岩桩，要求进基岩0.5m即停钻。钻孔桩设计直径为
In 1985, our team was entrusted by the Wenzhou Marine Fisheries Company and assumed the construction task of the bored pile foundation of the company’s ration fishery workshop. The ration fish workshop is built on the edge of the Minjiang River, and its foundation was originally intended to improve the bearing capacity of the strata using the strong ramming method. However, after the engineering investigation, it is known that the underlying bedrock is tilted 30’ from the southwest to the northeast, and therefore it is feared that after the completion of the workshop, there will be a slip phenomenon along the surface of the bedrock under the heavy load, thus strengthening the foundation of the foundation. The method was changed to bored pile foundation. The type of column is made of rock-socketed piles, and 0.5m of bedrock is required to stop drilling. Bored pile design diameter is
