This paper refers the case project of the running tunnel from grand theater to science museum in shenzhen metro , through fem numerical simulation , researches the ground surface settlement and influence on the underground pipeline in soft stratum abundant with water by the technique of horizontal jet grouting 本文以深圳地铁一期工程大剧院科学馆区间中的近接双孔隧道工程为背景，对在富水软弱地层中应用水平旋喷桩工艺进行控制降水施工时对地表沉降及地下管线的影响进行了研究。
Two spherical waves and multiple spherical waves interference , and yang ' s interference experiments are simulated by using different methods . two spherical waves interference is focused on the on - plane or out - plane of the spot light source plane and the observing plane . then , we analyze how the temporal coherence of optical waves influence the contrast of the interference pattern 用光波波前叠加的方法实现了对两列球面波干涉、多光束干涉等实验的仿真；用传播矩阵描述衍射光波波前传播的方法对杨氏双缝和双孔干涉实验进行了仿真，并具体详细地分析了单缝衍射对双缝干涉的影响；另外还分析了光场的时间相干性对干涉条纹反衬度的影响。
