摘　　要：结合邹县电厂四期工程0号卸煤沟及转运站工程,介绍了在该工程深基坑开挖中使用的预制桩、钻孔灌注桩锚杆支护技术及架设的铁路线路跨越基坑施工便桥,并应用ANSYS软件对12m基坑的施工过程进行了模拟,结果显示此模拟技术能较好反映实际开挖过程,对同类工程有借鉴意义。With the outline of No. 0 coal unloading ditch and transfer station in the Fourth Zou County Project as an example, the paper introduces techniques used for the underground foundation pits. The techniques include the pre-stressing geotechnical anchoring technique of jack-up piles and pre-east piles and the makeshift bridge spanning the underground foundation pits that lie under the existing railway. By means of the ANSYS, the construction process of the 12-meter underground foundation pit is simulated. The result shows that the simulation can reflect the practical process of excavation. It may serve as a reference for similar projects in future.
