The highway from Xichang to Panzhihua is an important economic arterial road run-through Sichuan from south to north. Approximate one hundred of the highway go on Xigeda strata. Xigeda strata is the stillwater sediment of astatic lake facies at early stage of Quaternary Period. Because of soft lithology, low intensity and very bad stability the strata is well-known in China.

In this paper we combining connecting tunnel project of Subway Line 4 at Xidan-lingjing bystreet in Beijing. To aim at the difficulties of building large-span connecting tunnels in the fine sand layer, through roads and underground pipelines, construction nearby buildings and other project difficulties. Using theoretical analysis, numerical simulation, field tests and other research methods to comprehensive and systemic research the stratum deformation mechanism and process control techniques of shallow excavation method, and a series of results were obtained. Firstly, use the stochastic media theory to analyze the stratum deformation mechanism, concretely analyze the analytic equation of surface horizontal displacement and deformation which were caused by the excavation of single-hole and double-hole tunnel, and further discussion on ground settlement, vertical deformation, surface horizontal displacement and horizontal deformation. Analyzing the main influence factors of surface displacement, and combined with practical work to proof the theory which was applied to shallow buried single-hole tunnel in fine sand layer was scientific.

Compression and inversion action make series of traps, tectonic traps and stratigraphy traps are the primary trap types, Tectonic traps can be classified into anticlinal traps (compressional anticlinal trap, drape anticlinal trap, faulted anticlinal trap) and fault block trap (scalariform fault block trap, arcuate fault block trap, crossed fault block trap). Stratigraphy traps can be classified into stratigraphic onlap trap and stratigraphic erosion unconformity trap.

后期受挤压、反转作用的影响形成了一系列的圈闭，主要的圈闭类型有构造圈闭和地层圈闭，构造圈闭又可划分为背斜圈闭(挤压背斜圈闭、披覆背斜圈闭、断裂背斜圈闭)和断块圈闭(阶梯状断块圈闭、弧形断块圈闭、交叉断块圈闭)；地层圈闭可分为地层超覆不整合圈闭和地层削蚀不整合圈闭。
