The adaptability of arch dam to geology is more and more high, when the influence of complicated geology is considered, and the widespread used modern calculating methods in engineering, such as the finite element method, is considered during optimization design, the new challenge to old optimization design system of crown cantilever analysis is the full-automatic calculation problem of the different condition, different arch dam parameter, the possibility and the efficiency which were caused by the increments of calculation time.

高拱坝设计对地质条件的适应性要求越来越高，优化设计时要考虑到复杂地质条件的影响，最好采用已被工程界普遍接受的有限单元法等现代计算方法，这对以拱梁分载法为主的拱坝优化设计体系提出了新的挑战，除了需要解决不同条件、不同拱坝参数的全自动计算问题，还要解决由于结构计算时间增加所带来的优化计算的可行性和效率问题。

The Xuefeng mountain highway tunnel, which is to be constructed, is the most deep-lying and longest tunnel in our country.

邵怀高速公路雪峰山隧道是目前我国拟建埋深最大和最长的公路隧道之一，地质条件较为复杂，岩爆问题和大变形问题是该隧道的主要工程地质问题。

In the process of engineering construction of deep-lying long tunnel s,some geological hazards will be met because of the great depth and length and complicated geological background.

深埋长隧道延伸长、埋深大、地质条件复杂，工程建设中常会遇到一系列的地质灾害问题。

The excavation surface model of the composition geologic strata for the shield machine was established, in which the soft soil and hard rocks are taken into account simultaneously. In terms of the cutting mechanism of the individual disc cutter and drag scraper, the total bending moment model on the cutterheads of shield machines was proposed. The bending moment behavior was discussed when the shield machine excavates in the composition geologic strata.

针对盾构机在掘进过程中上软下硬的复合地质结构，建立了其刀盘截面圆模型，基于单个切削刀和盘形滚刀的切削机制，建立了复合岩土层掘进时刀盘平面内总弯矩分析模型，分析了与刀盘接触的撑子面内，不同软土面积分数的复合地质条件下，刀盘旋转掘进过程中的弯矩动态特性。

This paper expounds the geology disasters of the strip mine,and investigation for the flood control and drainage management in the mine district and surrounding area,the city flood control plan and geology disaster control plan and executing,and compares their reason formed and rainfall inducement and watercourse transmission flood,and put forward the existing issues.

本论文对西露天矿地质灾害情况，矿区防、排水及矿区周边河道防汛安全情况进行了调查，同时考察了城市防洪预案和地质灾害预案的编制及执行情况。

During well drilling, LWD monitoring device, comprehensive logging device, cutting logging, seismic interpretation, geologic models, and many other technical measurements had been used for real-time monitoring and comprehensive analysis. What had been done helped geosteering, and the putting forward of drilling track. The horizontal wells drilled in ultra thin single sand layer with the thickness of less than 2m, and the penetration rate for sandstone was higher.

在现场钻井过程中，采用LWD监控仪、综合录井仪、岩屑录井、地震解释、地质模型等多种技术手段相结合，实时监控，进行综合分析，为地质导向提供依据，并准确地指导了钻井轨迹运行，实现了在不到2m的超薄单砂层中穿行，达到了较高的砂岩钻遇率，并成功的穿越了小断层，实现了二次着陆。

Because of the uncertainty of the geologic information in the front of tunnel driving face, there are many geological disasters, such as landslide, gushing water, sudden mud, rock burst etc, in the tunnel excavating process, which cause the enormous economic losses and even casualties.

中文摘要：在隧道工程的开挖过程中，由于掌子面前方地质条件的模糊性，往往会伴随着塌方、突水突泥、岩爆等地质灾害的发生，造成大量的经济损失甚至人员伤亡。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
