The study results reveal some laws : ( 1 ) two failure modes exist in different obliquity slope and influence the internal force of soil nailing ; ( 2 ) the connection between face shield and soil nailing determines the distribution of the axial force along length ; ( 3 ) the influence of face shield involves its connection with soil nailing and its stiffness on soil nailing wall ; ( 4 ) the transversal effect of soil nailing depended on the joint of nail head is little ; ( 5 ) the maximum axial forces of other soil nailings except the first soil nailing increase gradually with excavation
研究表明： （ 1 ）素土坡隨著坡角的變化，存在兩種破壞方式，破壞方式不同，土釘受力狀態不同； （ 2 ）土釘和面層的連接方式決定著土釘長度方向上的軸力分佈形態； （ 3 ）面層主要通過面層與土釘的連接和面層的本身剛度兩個方面對土釘內力和墻體變形產生影響； （ 4 ）土釘橫向抗剪抗彎作用的發揮程度和土釘釘頭的連接方式有關，但作用不大，實際設計時可以忽略其影響； （ 5 ）隨著坡體的開挖，第一排土釘的最大軸力變化不大，其它土釘的軸力都穩步增加。 -
In this thesis, analysis of whole performance and interior mechanism of plain soil slope and soil nailing wall with flag finite difference program has been carried out. at the same time, the impacts on the internal force distribution of soil nailing and the deformation of soil nailing wall of many factors, including the connection between face shield and soil nailing, the friction decline between soil nailing and soil, the shear force & bending moment resistance of soil nailing, the cement crack in soil nailing, face shield, excavation, the obliquity of slope, and so on are studied in this thesis
本文通過flac有限差分程序，分析了素土基坑和土釘墻體的整體性能和內在機理，研究了土釘和面層的連接變化、土釘表面性能的下降、土釘的橫向抗剪抗彎作用、土釘漿體的開裂、面層的有無、基坑的開挖過程、基坑放坡角度等因素對土釘內力分佈和土釘墻變形的影響。 -

The direction guidance system plays an important part in the shield excavation, such as the prevention of snake motion, the reduction of ground settlement of tunnel construction and the insurance of tunnel quality etc. based on the principle of guidance system, a precise direction guidance system with high accuracy, high efficiency and more reliability is developed, it has the advantages of less times of surveying, real time positioning and shield behaviors monitoring
盾構導向系統是盾構掘進時的指揮系統，對指導盾構掘進、隧洞貫通、減少地表沉降以及保證隧洞的質量等具有重要的作用。本文在研究盾構導向工作原理的基礎上開發研製了一套盾構導向系統，精度高、工作可靠，可極大地縮短導向測量的時間和減輕勞動強度，實現了盾構掘進的實時定位和姿態監測。 -
For shield excavation the scope of reinforcement is determined either in vertical direction along the tunnel or in radial direction at its starting position
