Research on individual bamboo biomass and timber physical structure indicated that the allocation of Guadua amplexifolia biomass to branch is higher than moso-bamboo evidently. Root shoot ratio is larger than other sympodial bamboo, so it can be considered as a good breakwind plant because of developed root and branch. Every modularity biomass above ground had significant positive correlation with basal diameter and total height, it can simulated with allometric model. The culm had large relative wall thickness and low moisture content, so it can be cultivated as fine timber-used bamboo.

通过对Guadua amplexifolia现存单株生物量结构和竹材物理结构研究，结果表明：地上部分生物量在枝条上的分配比例高于相同径级毛竹，根冠比较其他丛生竹种大，具有发达的地下根系且易形成密集林分，是良好的防风植物材料；地上部分各器官生物量与地径、全高均呈显著的正相关，可以用相对生长模型进行模拟；竹秆有较大的相对壁厚和较低的含水率，可以作为良好的材用竹种进行培育。

结果表明：采场下盘边坡岩性条件较好，稳定性较高，总体边坡角均有可能进行加大、加陡：上盘边坡岩性条件相对较差，且地下水位较高，边坡的稳定性相对下盘较差。

Stiff layer beneath pavements and dynamic effects may affect falling weight deflectometer tests obviously. It is possible to estimate the depth to stiff layer or water table, if the effects are recognized thoroughly.

By the numerical analysis of the ultimate bearing capacity of two- and three-dimensional footing under combined loading mode, the results show that the effect of alteration of underground water lever on bearing capacity of three-dimensional foundation is more than on that of two-dimensional foundation, the effect of soil gravity on bearing capacity of three-dimensional foundation is more than that of two-dimensional foundation. At the same time, the numerical calculation process of ABAQUS indicates that whether the geostatic stress is balanced or not has great effect on the numerical convergence. In view of the effect extent of dilation angle of soil on the ultimate bearing capacity and the failure pattern of foundation, the condition of two-dimensional plane strain is higher than that of the three-dimensional foundation.

复合加载模式下，通过对三维矩形基础和二维条形基础进行数值分析，结果表明：黏性土地基中地下水位的变化，对三维矩形基础极限承载力的影响程度高于对二维条形基础的影响；在求解地基极限承载力的过程中，土体重度对三维矩形基础的影响明显高于对二维条形基础的影响，同时ABAQUS数值计算过程表明，地基土体地应力能否合理平衡，对数值求解过程中是否收敛有很大的影响；就土体剪胀角对地基极限承载力的影响程度而言，二维平面应变情况下土体剪胀角对极限承载力的影响比三维情况下的影响更明显，即土体剪胀角对条形基础极限承载力的影响高于三维矩形基础。

Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.

为弄清草地植被及其土壤环境对水淹干扰的响应，在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带，并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究，主要结果如下：(1)在植被的功能群组成中，随干扰强度的增加和水淹干扰持续时间的延长，湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的，中生、中旱生类植物功能群的优势度比例则逐渐减小，而一年生植物的优势度比例呈单峰型变化，地下芽植物比例增加，地面芽植物比例减小。

The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field , deformation field and stress field in heating process , which makes the particles of oil shale deform incompatibly : and the release of product pyrolysis results in irreversible damages of oil shale material and structure . These are the main reasons for the thermal fracture of oil shale .

研究结果表明：组成油页岩各种矿物颗粒热膨胀和弹塑性性质的不同及其分布的随机性，导致油页岩加热过程中温度场，变形场和应力场的非均匀性，使得油页岩颗粒间变形不协调和油页岩热解产物释放引起油页岩材料与结构性能发生不可逆的劣化损伤，这是油页岩发生热破裂的主要原因；热传导方式加热油页岩，温度的传递比较缓慢，加热井和生产井的间距不宜过大，对油页岩储层性质存在差异时，注热井应选择较高热导率的区段；油页岩的层理对油页岩地下原位开发形成渗透带至关重要，油页岩达到热解温度会产生附加的膨胀力，首先在层理处开裂，应充分利用油页岩层理赋存条件改造其渗透性。
