objective to elucidate the choice of three defferent ways as well as the clinical efficacy in the treatment of pilon fracture and different damages of skin and tissue.methods 29 cases were treated with calcaneum bone traction and small splinting,23 cases were treated with internal fixation,11 cases were treated with external fixation of ilizarov.results all cases were followed up for 8～31 months (15.3 months average).according to helfet criterion,the results were evaluated as the total excellent and good outcome accounted for 90.5％.conclusion the key point of treatment is rational selection of three defferent ways in the treatment of pilon fracture according to the typle of pilon fracture and different damages of skin and tissue.

Typically, capitellar fractures are divided into 3groups3,21: type 1, the Hahn-Steinthal fracture, is characterized by a single, large capitellar fragment; type 2, the Kocher-Lorenz or Mouchet fracture, involves the articular cartilage and a thin layer of subchondral bone; type 3 was originally described by Broberg and Morrey and characterizes a comminuted or compression fracture of the capitellum.

肱骨小头骨折可典型地分为3种：1，Hahn-Steinthal骨折，特点为单个、大块小头骨折片；2，Kocher-Lorenz 或 Mouchet骨折，涉及到软骨和软骨下骨骨折；3，此类骨折最初为Broberg和Morrey所描述，特点为肱骨小头粉碎性或压缩性骨折。

The test results show that both the permeability of sandstone and that of granite with a single fracture declines with the increasing effective pressure, following the law of exponential decay. The permeability sensitivity of granite with a single fracture to effective stress is much stronger than that of sandstone, but the recovery capability of permeability of sandstone is more stronger than that of granite with a single fracture.

试验结果表明，在围压升降过程中，砂岩和单裂隙花岗岩的渗透率均随有效应力的增加呈负指数规律减小，但单裂隙花岗岩的渗透率对有效应力的敏感程度远大于砂岩，而砂岩渗透率的恢复程度则远大于单裂隙花岗岩。

The main objective of this dissertation was to develop methodologies with capability of engineering application for simulating flow in fractured rock using discontinuum models. The study work includes three parts. In the first part, numerical methodology of three-dimensional discrete fracture network model casing on hybrid BEM-channel was presented, and the technique for improve the model's computing efficiency was also studied. Firstly in this part, computer simulation methodology based on the Baechermodel for generating network of discrete fractures was presented, which includes the follow details: probability distributions of fracture density,orientation, trace length, size, and aperture and estimation of their statistical parameters; stochastic models of fracture network; Monte-Carlo's simulation method; numerical simulation procedure and technicality.
