雄安开展万米地下调查:地上地下将打造两个雄安

2017-06-26 07:27:46   新华视点

在标准孔中开展第四纪研究、地层描述、标准贯入试验、波速测试、综合物探测井等工作,采集系列原状样品、扰动样品、易溶盐样品和第四纪样品等测试样品,进行土工试验获取土体力学参数。

通过标准孔施工,全面研究0~200米第四纪地层结构、岩性特征、岩相古地理条件、以及土体力学性质,建立第四纪和工程地层分层标准,编制工程地质标准柱状图和工程地质标准剖面,为研究雄安新区工程地质条件、评价土体承载力提供标准,为建立0~200米三维地质结构提供基础资料。

中国地质调查局水环部负责人郝爱兵表示,雄安新区将成为我国“空间、资源、环境、灾害”多要素城市地质调查试点的第一个示范区。针对国土空间规划、资源合理开发利用、生态地质环境保护、地质灾害防治、城市文化建设等方面需求,将统筹建立深部探测国家实验室、城市地质调查国际交流与展示中心、支持服务雄安新区的地质专业中心和科普基地,为后工业化时期地质调查转型提供示范基地。

地下地上:

打造“两个雄安”

千年大计,安全第一。地调调查显示,雄安区域地质构造稳定,地面沉降和地裂缝较轻,没有制约城市规划建设的重大地质安全问题。

雄安新区及邻近地区地质构造稳定,地下深部分布有三条隐伏基岩断裂活动微弱,基本不会对工程建设造成影响。区内近千年未发生过6级以上地震。1970年有现代地震监测记录以来,未发生过3级以上地震。

说起京津冀腹地,人们就关心地面沉降。调查表明,区内工程地质条件总体较好。绝大部分地区累计沉降量小于500毫米,是华北平原地面沉降发育程度较轻的地区。

国土资源部部长姜大明多次提出,参照国际经验,在土地资源约束条件下,我国城市要向地下要空间。“地下雄安”前途无量:区内地下100米深度内以粘性土为主,仅在26至40米深度分布连续含水层。总体上土体结构较均匀、颗粒较细,砂层分布较少,工程施工条件好,十分适宜地下空间开发利用。

为保护地下26至40米深度的连续含水层,中国地质调查局建议地下空间分浅层(埋深0至26米)和中深层(埋深40以下)两个层位规划开发。

浅层地下空间上部可作为仓储购物、生活娱乐、停车场和民防工程等建设空间,下部可作为综合管道、地下交通等建设空间;中深层地下空间上部可作为地下交通、物流通道等建设空间,下部可作为储水管廊、特种工程等战略基础设施建设空间。
