刚性桩复合地基特别是CFG桩复合地基,因其充分利用桩间土承载力、造价较低、施工速度快及工艺较成熟等优点得到广泛应用,关于其设计计算的相关软件也较多,如理正、同济启明星等,但其不足之处为需要根据地层参数,对不同的桩长及桩间距进行多次试算复合地基承载力及沉降量,且两者不能相互结合,重复工作量较多,设计计算效率不高,为提高复合地基处理设计的效率及质量,文中在已有相关软件的基础上,基于Visual Basic语言,并根据最新的规程规范,编制了刚性桩复合地基设计计算程序,以适应当今快节奏、低成本的市场竞争环境。
Rigid pile composite foundation, especially CFG pile composite foundation, has been widely used because it takes full advantage of the bearing capacity of soil between piles, lower cost, faster construction speed and more mature technology. There are also many related softwares for its design calculation, such as Ligong, Tongji Venus, etc. However, the shortcoming is that it is necessary to carry out multiple trial of bearing capacity and settlement of composite foundation with different pile length and pile spacing according to formation parameters, and the two can not be combined with each other and the workload More design and calculation efficiency is not high, in order to improve the efficiency and quality of composite foundation design, based on the existing software, based on the Visual Basic language, and according to the latest rules and regulations, the rigid pile composite foundation design and calculation Program to adapt to today’s fast-paced, low-cost market competition environment.
