  5. The primary contents are as follows : 1. according to the feature and the theory of shield tunnel construction, based on the factors that cause effects on environment, the workable monitoring project is established, which include principles of design, the selection of monitoring cross section, the layout of monitoring points, monitoring content and materials feedback. such as operation program, selection of earth pressure, wall - back grouting, rectification of shield machine, which are used to reduce the effect of construction on environment, are analyzed in detail

    完成的主要研究內容如下： 1 、根據盾構法的施工特點及原理，在明確了盾構施工安全影響因素的基礎上，從監測方案設計原則、監測斷面的選擇、監測點的布置、監測內容以及信息反饋等出發，提出行之有效的監測方案；詳細分析了掘進模式、土壓力選擇、壁后注漿、盾構糾偏等施工控制手段，用來減小盾構施工對周邊環境的影響。
  6. ( 2 ) the method of finite element discrete and optimal parameter back analysis is adopted. ( 3 ) concentrated on the question of high external water pressure of the deep - lying tunnel, the basic theory and method calculating external water pressure are systematically studied. ( 4 ) based on jinping cascade 2 hydropower station, numerical simulation rain infiltration of seepage field under different drainage pattern and grouting pattern are studied, also, the high external water pressure is analyzed and studied and some seepage control measures are put forward

    （ 2 ）採用有限元離散?優化法進行參數的反演分析； （ 3 ）針對深埋隧洞的高外水壓力問題，進一步分析和研究了襯砌水荷載及外水壓力的作用機理和計算方法； （ 4 ）以錦屏二級水電站深埋長引水隧洞作為本文的主要研究對象，採用考慮降雨入滲滲流場分析的方法對排水方案和灌漿封堵方案不同情況下的滲流場的水頭分佈進行了數值模擬，並對其外水壓力進行了分析和研究，提出了滲流控制的具體措施。
  7.
