【摘   要】   装配式建筑软土地基加固过程中，软土土质不均匀，地基下沉数值过大，导致装配式建筑与软土地基间的一致性参数过小，针对该问题，在装配式建筑软土地基加固流程优化中应用BIM技术。以实际软土地基建筑工程各项参数为基础，构建装配式建筑模型，根据不同软土层的土质结构，优化软土地基加固流程，控制加固过程中产生的软土层下沉。选用已知参数的应变计作为实验器材，设定软土层结构并安置应变计。实验结果表明，应用BIM技术的流程优化方法产生的地基下沉数值最小，装配式建筑与软土地基间的一致性参数符合标准。

【Abstract】    In the process of soft soil foundation reinforcement of prefabricated building， the soil quality of soft soil is not uniform and the settlement value of foundation is too large， which leads to the problem that the consistency parameter between prefabricated building and soft soil foundation is too small. Aiming at this problem， BIM Technology is applied in the process optimization of soft soil foundation reinforcement of prefabricated building. Based on the parameters of practical soft soil foundation construction engineering， the prefabricated building model is constructed. According to the soil structure of different soft soil layers， the reinforcement process of soft soil foundation is optimized， and the settlement of soft soil layer produced in the reinforcement process is controlled. Finally， the application research of BIM Technology is completed. The strain gauge with known parameters is selected as the experimental equipment， the soft soil structure is set and the stress gauge is installed. The experimental results show that the settlement value of the foundation generated by the process optimization method of BIM Technology is the smallest， and the consistency parameters between prefabricated building and soft soil foundation meet the standard.

0     引言

随着城市人口不断增长，装配式建筑应用更加广泛[1]，装配式建筑在实际施工时一旦稍有纰漏就会产生质量事故[2]。软土地基指的是强度低、压缩量较高的软弱土层，具有高压缩性，但是抗剪强度低、透水性低，该土层中含有一定的有机物质，较低强度的软土层会形成大面积的沉积量，影响整体地基结构的稳定。在BIM技术参与下，本文以实际装配式建筑参数为基础，结合软土地基的发展特性，模拟实际建筑地基工程环境，优化地基加固流程，消除地基结构中的安全隐患[3]。

在上世纪80年代末，国外学者提出了BIM的概念，在高精度计算机硬件技术的支持下，BIM技术逐渐成为建筑工程中的一项重要技术[4]。国内起步较晚，在本世纪初才开始BIM技术的研究工作，各个高校逐渐建立起BIM的课题研究组，制定适合我国建筑风格的BIM规则，如今已经进入到高速发展的阶段[5]。……
