拉裂

The feature of typical multiple rotational loess landslides is: large scale, deep sliding face, three-five sliding face cascades, single landslide with the "plough" structural character of behind high and sheer-middle subdued-front tilt. The main formation mode of landslide is creeping-sliding-tensile fracturing. The failure modes contain extensive rotation sliding, digressive rotation sliding and compound rotation sliding.

2典型多级旋转型黄土滑坡特征表现为：规模大、滑带深、3-5级滑面分层叠置、单个滑面成后缘高陡-中部平缓-前缘微翘的"犁式"结构特征；其变形破坏方式表现为：蠕滑-滑移-拉裂-块体滑动-旋转-逐级扩展，其扩展方式主要包括：扩展式旋转滑动、渐灭式旋转滑动和复合式旋转滑动。

Geographical disaster resulted in soil movement and ground deformation, so buried pipeline will occur bend,compress,distort,rip,and part flection and other breakage activities.

地质灾害引发土壤运动和地表变形，从而导致埋地管道产生弯曲、压缩、扭曲、拉裂、局部屈曲等破坏行为。

The basal contact friction experiment is adopted to simulate surrounding rock's deformation in all phases after excavating the tunnel ,thus we can get that the deformation is divided into three phases: incurvate－ripping－collapse.

采用底摩擦试验方法对隧道开挖后围岩变形各阶段进行模拟，由此得出该隧道开挖后围岩的变形过程分为弯曲内鼓－拉裂－折断塌落三个阶段，其结果与现场定性判断相吻合。

According to the relevant datums and field investigations, the paper makes No. 316 national highway in South region as research region to analyze the conditions of inoculating disasters and slope s transform destruction model and draws such conclusions:(1)Many factors such as terrain, geomorphic, lithosome and solum character, geologic structure, neotectonic movement, rainfall condition, groundwater trait, anthropokinetic and so on influence on the study region, which make the geological disasters occurred frequently and generate enormous hazards.(2)The geological disasters have such distribution characteristics: terrain and tectonic make geological disasters development of osculating correlated property, relative concentrate property, packet property, periodic property and so on.

本文首先在搜集相关资料和野外调查的基础上，以陕南316国道公路为重点研究区，全面分析了研究区域内地质灾害的孕灾条件与斜坡变形破坏模式，得到了以下认识：(1)研究路段地质灾害的发生发展主要受控于区内地形地貌、岩土体特性、地质构造与新构造运动、降雨条件、地下水特征及人类工程活动等因素：(2)研究路段发育滑坡、崩塌、泥石流和危险斜坡等四种地质灾害，具有如下的分布特征：地势与构造对地质灾害发育的密切相关性、相对集中性、群发性、周期性等；(3)研究路段斜坡地质灾害主要有六种变形破坏模式分别为：顺层滑动破坏、蠕滑—拉裂变形破坏、弯曲—拉裂—剪断破坏、旋转式滑移—拉裂破坏、楔形体滑动破坏、堆积层沿基岩面的滑动破坏模式，而且斜坡灾害的变形破坏往往是多种模式的组合。

Secondly, by the numerical simulation "experiments" and mechanics analyses, the effects of temperatures, forming velocities and the entering angles of mould on the products were studied. The main invaliding forms both of crinkling and crazing were simulated and analyzed, so that the technical parameters of forming, geometrical parameters of moulds were optimized.

其次，通过对TC1钛合金薄板整流内罩的深拉热成形的数值模拟&实验&和力学分析，探讨温度、成形速度和模具压边力等对成形产品的影响，模拟分析了&起皱&和&拉裂&等主要失效形式，对成形工艺参数、模具几何参数等进行了优化。
