| 摘 要： | 西汉时期,贾让提出"治河三策",成为治理黄河的最早文献。"三策"后来被王景应用于治理黄河的实践中。析读《治河三策》,笔者认为贾让提出的"不与水争地"、顺自然而用之的思想,以及实地考察、比较分析而后形成决策等科学精神,仍然值得我们重视。

| Abstract: | In order to understand goodly the reinforcement mechanism of the pile-anchor and soil nailing combined structure, optimal de- sign and numerical simulation for a large deep excavation pit with pile-anchor and soil nailing in Zhengzhou city were done, the process of pile-anchor and siol nailing combined supporting was numerically simulated by the software FLAC3D, the displacement field of the pit and the change of the stress of siol-nail-anchor structure Cell were analyzed. The simulation results were basically consistent with the design calculations results. The results of numerical simulation had effectively guidance to design and calculate, and in-site construction process. |
