本文通過對國內電信發展現狀進行統計分析，探討我國電信業改革的必要性，同時通過對電信市場管制理論、手段、任務及其內容進行分析和通過對電信管制對運營企業的經濟影響的深層次分析，提出對我國電信市場管制的策略及具體對策。 -
Through the numerical calculation for improved soil layers, there is an economical and reasonable improved zone whose depth is a constant but whose width is decided by the controlling residual deformation of subway structure. and a empirical formula for the subway residual deformation is given which can consider the improvement depth and width
通過對加固后的地基進行多次有效應力模擬，發現南京市地鐵地基合理的加固深度基本上保持不變，而合理的加固寬度則可由控制震后殘余變形來決定，並給出了計算加固后的地鐵隧道震后殘余位移經驗公式。 -
It was shown that the measured active soil pressures were smaller than the theoretical values and diminished with time, the measured pore water pressure decreased with the time and increased with the depth of soil, the combinative effects of cap girder and supporting structure were obvious which diminished the displacement of foundation pits, and the measured axial force of the anchor and interior steel beam were far less than the design force, indicating that the design safety factor of the foundation pit was too large to be economical
基坑工程實行信息化施工並獲得了豐富的監測數據，通過對數據分析結果表明：實測主動土壓力小於計算主動土壓力，實測主動土壓力隨時間延長變小：土體中孔隙水壓力隨時間增長而減小，孔隙水壓力隨深度增加而呈非線性增加；基坑冠梁協同作用明顯，冠梁減小了基坑變形；錨索軸力比較穩定，鋼撐軸力變化相對較大，且二者軸力仍富餘較大，該設計比較安全。
