护岸工程基坑边坡稳定性计算传统方法与数值模拟法的对比

针对航道整治工程中护岸结构的基坑边坡易发生的滑坡坍塌问题,以浙江北部某航线的航道整治工程为例,对该工程的边坡稳定性问题采用传统极限平衡理论的条分法和数值模拟的FLAC3D方法进行对比分析。相比条分法,FLAC3D法分析条件更加完善,在理论上更加可靠,也能对边坡详细区域进行分析,以便进行针对性预防。而条分法计算理论理想化,计算结果偏保守。

Comparison between traditional method and numerical simulation method for calculating slope stability of foundation pit in bank protection engineering

Aiming at the problem of landslide collapse in the foundation pit slope of the bank protecting structure in the waterway regulation engineering,taking the waterway regulation engineering of a route in northern Zhejiang Province as an example,the stability of the slope of this project is compared and analyzed by using the traditional article points method based on the traditional limit equilibrium theory and the numerical simulation FLAC3D method.The FLAC3D method is more perfect than the article points method in terms of analysis conditions and more reliable in theory.It can also analyze area of the slope in detail for targeted prevention.The calculation theory of article points method is ideal,and the result is conservative.
