浅议土地供应制度的改革

根据我国现行法律、法规，集体建设用地与国有建设用地存在“待遇”上的巨大差异，集体建设用地是农民最重要的财产，集体建设用地与国有建设用地不平等的“待遇”，使集体建设用地不能以市场方式有效地合理配置，影响到农业、农村和农民稳定与发展。允许集体建设用地流转，改变土地供应制度，建立以土地用途管制为核心的城乡建设用地统一的市场，建立农民土地保障基金机制是保护农民土地财产权，提高生产力发展水平，增加农民收入的要求。

考虑内力状态的大跨高墩连续刚构桥地震易损性分析

为研究考虑内力状态的连续刚构桥的地震反应及易损性情况,以一座非规则大跨高墩连续刚构桥为对象,基于MIDAS/Civil和OpenSees平台分别进行施工过程模拟和非线性动力分析,并采用等效荷载法将内力等效荷载附加到OpenSees模型上,使其处于对应的等效内力状态;选取40组典型的速度脉冲型近断层地震动记录为输入,采用增量动力分析法进行考虑内力状态的地震易损性分析,对比分析了考虑内力状态与否对连续刚构桥地震易损性的影响。结果表明:所采用的内力等效荷载方法能够较好地考虑成桥内力状态;考虑内力状态与否对成桥阶段主墩和引桥墩的地震易损性具有很大影响,不考虑内力状态时将严重低估主墩和引桥墩的地震损伤概率。     

三维地质建模过程中综合地质剖面构建方法研究

综合地质剖面是三维地质建模重要的数据源,在地质构造复杂地区运用综合地质剖面构建三维地质模型的方法应用较为广泛。本文以成都市为例,详细介绍了综合地质剖面构建需要准备的地质资料、剖面的部署原则和构建方法,并解决了剖面构建过程中遇到的同时代、同层位的不同地层之间的连接问题。实践表明,通过综合地质剖面的构建,可以充分发挥地质技术人员在三维地质建模中的主观能动性,准确刻画复杂地质体在三维空间的展布情况,有效实现复杂地质体交互式半自动建模,提高三维地质建模的效率和精准度。     

雄安新区地上地下工程建设适宜性一体化评价

为支撑雄安新区总体规划编制,2017年6月至8月,中国地质调查局在雄安新区组织实施了大规模工程地质勘察工作。以典型示范区为例,探索了地上地下工程建设适宜性一体化评价方法,并利用该方法对雄安新区全区进行了评价。结果显示:雄安新区建设场地稳定性较好,稳定场地和基本稳定场地占89.5%;雄安新区工程建设适宜性好,全区均适宜或较适宜工程建设,平均深度15~20 m、35~45 m、55~70 m的3段地层土体承载力普遍较高,可优先作为多层、高层、超高层建筑物复合地基或桩基的桩端持力层;雄安新区起步区地下空间开发利用条件优越,建议将70 m以浅地下空间分3层进行规模化开发利用,充分开发利用30 m以浅的浅层地下空间,适度开发利用30~50 m次深层地下空间,超前规划利用50~70 m深层地下空间;建议加强地下空间开发与浅层地热能开发利用的统筹协调。局部存在地面沉降、地裂缝、砂土液化、软弱土等不良工程地质问题,在控制性详细规划和岩土工程勘察中应加以重视。
