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.

Analyzed on the tunnels that used EPB method in different soils, the more logical three-dimensional finite element model is based, which can reality represented the soil transfiguration. 3 Due to the engineering example, a 3D FEM simulation model was founded. The model was used to study the rules of soil deformation and surface settlement during shield tunneling. 4 The characteristics of loess include the module, conglutination force and inner friction angle of the loess, affected the soil deformation. 5 The influence factors to the surface settlements such as the depth of soil, the outer diameter of the shield tunnel, the released stress at the cutting face, the fill ratio of the shield tail void, pouring-slurry press, thrusts and lengths of shield and digging steps were studied using the FEM method. References is brought forward in the loess areas of Xi'an was proposed.

The conception, studied objects and basic constituents of non-Smith strata are elaborated from theory level: Non-Smithian strata are the strata that have undergone mixing of different degrees, thus were deformed, metamorphosed and displaced into disorder totally or partially. They are the disorder parts in orogenic belts. Melange is the solo studied object of non- Smithian stratigraphy. The slices in melange is one of the basic constituents of non- Smithian strata, and also one of the basic units in the non-Smithian mapping. The slices used in this paper refer to blocks divided by small-scale tectonic boundaries and have certain constitutes. Superslices used in this paper refer to a set of slice association with similar tectonic deformation bounded by large-scale tectonic mixing.
从理论上阐述了非史密斯地层的概念、研究对象和基本构件：非史密斯地层（non-Smithian strata）是指那些经历过不同程度的混杂建造，并经历了变位，变形、变质，全部无序或部分无序的地层，主要指造山带地层中的无序部分；混杂岩是非史密斯地层的唯一研究对象；混杂岩中的构造岩片是非史密斯地层基本构件之一，亦是非史密斯地层和地质填图基本单位之一，岩片是指以构造拼合边界所分割的具有一定物质构成的地质体；物质建造形成于同一大的构造旋回期（如晋宁期、加里东期、海西期等）、亲源关系密切、大致经历了相似变形、变质历程的一套岩片组合体被称之为超岩片。
