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.

通过对不同土质条件下盾构法进行地铁隧道施工的有限元分析，全面反映盾构推进对土体变形的影响情况； 3根据有关勘测资料，建立合理的盾构法施工三维非线性有限元模型，对盾构法施工引起的地层变位和地表位移情况进行计算，分析了盾构施工引起的地层变形规律和地面沉降规律； 4研究了黄土特性(地基模量、粘聚力和内摩擦角)对盾构法施工中土体变形的影响； 5利用三维有限元对盾构施工过程中影响地面沉降的因素(覆土厚度、隧道外径、开挖面压力变化量、注浆压力、盾尾空隙填充率、开挖步长、盾构机的长度和推进力等)进行研究，为今后西安地区地铁的建设提供参考。

The development of highway constructed in the massif that terrain and physiognomy is very complicated, There appear many problems in the course of investigating, designing and constructing. Among them, the high soil slope because of digging is a typical example.

随着高等级道路建设将向地形地貌非常复杂的山岭重丘区发展，给勘察、设计和施工提出了越来越多新的课题，其中由于开挖形成的土质高边坡就是典型的一例。

The company has a complete technical service system, for you to do detailed measurements of soil.

公司有完整的技术服务体系，为您做详细的土质测量。

A loose, earthy, extremely fine-grained, natural sediment or soft rock composed primarily of clay-size or colloidal particles and characterized by high plasticity and by a considerable content of clay mineral and subordinate amounts of finely divided quartz, decomposed feldspar, carbonates, ferruginous matter, and other impurities; it forms a plastic, moldable mass when finely ground and mixed with water, retains its shape on drying, and becomes firm, rocklike and permanently hard on heating or firing.

中文解释=松散的、土质的、颗粒极细的天然沉淀物或软石，主要由黏土粒径大小或胶质的颗粒组成，特徵为具高可塑性，及大量的粘粒矿物，其次为的细小的石英、被分解的长石、碳酸盐、含铁物质和其他杂质；当精细研磨并和水混合后，可形成可塑的，适於模压的物质，乾燥后能维持形状，加热或烘烤时变得如岩石一般牢固，且长期保持坚硬。

Considering this limitation, we propose an optimization program, in which we select appropriate formula according to different soil.

针对此局限性，提出一种根据不同土质选用适当公式的优化方案。

So that at end of 20th century, the natural environment accumulated too much unconscionable results. Every kind of calamity happened frequently: bad-balanced precipitin, soil lapse, prolonged drought time, soil aggravation, life species decreased quickly, etc.

以至于在20世纪末，自然环境由于积累了太多的不合理开发的后果，各种灾害频频发生；降水不均、水土流失、泥石流、伏旱时间延长、土质恶化、生物物种骤减等等。

Numoerous civil engineering projects have been built on the silty sand layer on the western plain in Taiwan.

於台湾西部平原在台中以南、台北盆地以及东部的宜兰与花莲，皆有厚层的粉土质砂土，在此等土壤上进行的土木工程不计其数。

People use it to vertically stab the ground. The depth it can reach is 20 meters. The semicylindrical shovel will gradually take some underground earth out, and then dig a deep hole of more than 10 cnetimeter diameter. It is used for probing the underground soil texture, so that people would know whether there is ancient tombs or not.

使用时垂直向下戳击地面，利用半圆柱形的铲可以将地下的泥土带出，并逐渐挖出一个深洞，可达20米，用来了解地下土层的土质变化，以判断地下有无古代墓葬以及人类活动的遗迹。
