【摘要】 交河故城遗址在自然和人为环境的影响下,已经遭受了严重的破坏,交河故城的环境主要特点是风沙大,温差大,土体耐崩解性差,矿物成分的耐风化、热膨胀系数有差异,位于新构造活动带。它的主要病害有风蚀、雨蚀、裂隙、崩塌等,交河故城的破坏主要是这些因素的综合作用。通过对交河故城赋存环境和病害的调查,分析它的赋存环境因素对土遗址的作用机理,认为风是交河故城破坏的主要外动力,风蚀病害是交河故城的最主要病害,风参与了所有的破坏活动;温差变化大、雨蚀、地质构造和地震是它破坏的因素之一。温度变化引起土体内水分含量的变化是表层土体风化的主要因素;土体中可溶盐、方解石、长石含量高,是它抵抗破坏性能差的主要内因;同时,建议可用PS材料对它进行保护加固。更多还原

【Abstract】 The Ruins of Jiaohe is a national major preservation unit of cultural relic,It have already been seriously demolished by the natural and artificial environment,The main characteristics of the environment of The Ruins of Jiaohe is big sandstorm,the big difference of temperature,the bad slake durability of soil mass,the resist weathering and heat dilatability coefficient of the mineral is difference,located the new tectonic movement belt.Its primary damages is weathering,rain erode,cranny and collapse etc.The breakage of The Ruins of Jiaohe is these factors to synthesize effect.Pass to investigate the conservational environment and the damages of its,analyzing the action mechanism that the environment factor impact the earthen sites,thinking that the wind is a main outside power to the breakage of The Ruins of Jiaohe,The wind erode is most damage of The Ruins of Jiaohe,the wind participates in all sabotage;The great difference in temperature,rain erode,geology structure and the earthquake is one of the factor of its breakage.It is the primary factor of the surface layer soil weathering that the temperature variety bring on the soil internal water content variety.The bad capability to resist destroyed rest with plenty salt,feldspar,calcite within the soil.So the material PS is suggested to use.更多还原
