结构终极法 技术领域  Structural ultimate method
本发明属于地下空间资源开发利用领域。  The invention belongs to the field of development and utilization of underground space resources.
背景技术 Background technique
伦敦以地铁为轴线的地下空间资源开发利用， 被视为现代地下空间资源开发利用的 起点， 即城市现代交通的起点， 结束步行交通、 马车交通的历史。 地铁问世于 1863年， 当时世界上尚未发明汽车和开发石油， 25年后 （1888年） ， 德国奔驰汽车商业上市， 开 创人类汽车交通新纪元。 纵观现代城市交通， 其模式大概有三， 一是地铁交通单一模式 ( 1863年至 1888年） ， 二是地铁、 汽车交通多元和谐模式 （ 1888年至二战后） ， 期间 由于车少路多， 城市出现有轨电车； 三是地铁、汽车交通多元堵车模式（二战后至现在）。 随着人类社会经济发展和科技进步，城市交通模式应为动态模式，不能以不变应 "万变"。 半个多世纪前， 城市开始堵车， 今天已是限车 "治堵" ， 有车不能上路。 2000年世界 未来城市大会 《柏林宣言》 郑重宣称， 全世界城市没有一个做到真正可持续发展。 城市 "堵车"非一国一城 "独家新闻" ， 而是全球性的、 灾难性的。 城市交通堵塞等诸多弊 端总称为城市 "综合症" 。  The development and utilization of underground space resources based on the subway in London is regarded as the starting point for the development and utilization of modern underground space resources, that is, the starting point of modern urban traffic, ending the history of pedestrian traffic and carriage traffic. The subway was introduced in 1863, when the world did not invent cars and develop oil. 25 years later (1888), the Mercedes-Benz automobile commercial market was launched, creating a new era of human automobile transportation. Throughout modern urban transportation, there are about three modes: one is the single mode of subway transportation (1863-1888), and the other is the multi-harmony mode of subway and automobile transportation (from 1888 to the end of World War II). There is a tram; the third is the subway and car traffic multi-blocking mode (after World War II to the present). With the social and economic development of human beings and the advancement of science and technology, the urban traffic model should be a dynamic model, and it should not be changed in the same way. More than half a century ago, the city began to jam, and today it is restricted to "blocking", and there are cars that can't get on the road. The World Future Cities Conference 2000 The Berlin Declaration solemnly declares that none of the world's cities are truly sustainable. The city "blocking traffic" is not a country and a city "exclusive news", but global and catastrophic. Many disadvantages such as urban traffic congestion are collectively referred to as urban "syndromes".
多年以来， 人类社会迫切希望实现汽车地下化， 解决城市交通堵塞， 但只是纸上谈 兵， 并无实际进展。 汽车地下化不能实现的症结在于地下空间资源开发施工工法。 现有 地下空间主要施工工法有二： 一是基坑法； 二是盾构法， 基坑法施工不安全， 但能开发 任意地下空间； 盾构法施工安全， 但只能开发小空间一一隧道。 准确地说： 按现有岩土 工程理论开发任意地下空间， 地面道路两侧的建筑要倒塌， 对城市（建筑）而言是场"灾 难" ， 地下空间资源不能有效开发和合理利用， 汽车地下化受阻， 酿成城市 "综合症" 。 两害相权取其轻， 各国政府与国际社会对 "灾难" 和 "综合症"权衡利弊， 苦涩地接受 城市 "综合症" ， 认同城市 "综合症" 带来苦不堪言， 甚至令人恐惧的城市交通， 无条 件接受限车 "治堵" 措施， 这样残酷的现实全球城市必须面对， 无一幸免， 这就是人类 150年的城市交通史。 随着科技迅速发展， 汽车换代全方位启动， 城市交通换代刻不容 缓。 两者相辅相成， 汽车地下化， 城市交通和谐、 畅通。  Over the years, the human society has been eager to realize the undergroundization of automobiles and to solve urban traffic congestion, but there is no actual progress on paper. The crux of the failure of car undergroundization lies in the construction and construction of underground space resources. There are two main construction methods in the existing underground space: one is the foundation pit method; the other is the shield method; the foundation pit method is unsafe, but it can develop any underground space; the shield construction method is safe, but only the small space can be developed one by one. tunnel. Accurately speaking: According to the existing geotechnical engineering theory, any underground space will be developed. The buildings on both sides of the ground road will collapse. For the city (building), it is a "disaster". The underground space resources cannot be effectively developed and rationally utilized. The resistance is blocked, resulting in the city "syndromes". The two evils are taken lightly. Governments and the international community weigh the pros and cons of "disasters" and "syndromes", accept the city "syndromes" bitterly, and identify the city "syndromes" to bring misery and even fear. The urban traffic, unconditionally accept the restrictions on the "blocking" measures, so the cruel reality of the global city must face, no one is spared, this is the 150-year history of urban traffic. With the rapid development of science and technology, the replacement of automobiles has started in an all-round way, and urban transportation has not been delayed. The two complement each other, the car is underground, and the city traffic is harmonious and smooth.
现有地下空间开发利用模式为 "岩土工程 ·地下空间 ·地铁" 模式， 诠释为： 利用 岩土工程理论开发地下空间， 目的是建立地铁交通。 现有模式具有工程施工不安全： 不 能实现汽车地下化， 建立城市地下立体交通； 资源利用率低等诸多缺陷。 一味修建地铁 无助于城市交通畅通。  The existing underground space development and utilization model is "geotechnology · underground space · subway" mode, which is interpreted as: the use of geotechnical engineering theory to develop underground space, the purpose is to establish subway traffic. The existing model has unsafe construction: it cannot realize the undergroundization of automobiles, establish three-dimensional traffic in the city, and has many defects such as low resource utilization. Simply building a subway will not help the city's traffic flow.

(二） 开发法则  (ii) Development rules
开法法则是地下空间资源实施综合一次终极开发的设计规则， 分规划法则、 设计法 则、 实施法则三个层面。  The law of opening law is a design rule for the implementation of integrated and ultimate development of underground space resources, which is divided into three levels: planning rules, design rules, and implementation rules.
1、 规划法则  1. Planning rules
规划法则采用超前统筹规划法则。 规划法则是以城市交通 （汽车动、 静态交通） 需 求为依据， 使其汽车动、 静态交通等实现需求与供应相匹配。 所以， 又称为供需匹配规 划法则。 地下空间资源规划是以路段作为规划建设单元， 逐一形成地下交通网络， 确保 城市交通 （路、 车） 供需动态平衡。  The planning rules adopt an advanced planning rule. The planning rule is based on the demand of urban traffic (automobile and static traffic), so that its dynamic and static traffic can be matched with demand. Therefore, it is also called the supply and demand matching planning rule. Underground space resource planning is to use the road section as a planning and construction unit to form an underground transportation network one by one to ensure the dynamic balance of supply and demand of urban traffic (roads, vehicles).
2、 设计法则  2, the design rules
设计法则采用通用置换设计法则。 通用置换设计法则的核心是设计安全度取值， 结 构设计应根据超前统筹规划的项目， 设计荷载按最大值取用， 以及有关构造处理， 使工 程适应各种用途动态变化需求， 置换灵活方便， 达到通用的目的， 所以， 设计法则称为 通用置换设计法则。 因工程设计按最大荷载取值， 设计法则又称为最大荷载设计法则。  The design rule uses a universal replacement design rule. The core of the universal replacement design rule is the design safety value. The structural design should be based on the advanced planning project, the design load should be taken according to the maximum value, and the related construction processing, so that the project can adapt to the dynamic change requirements of various uses, and the replacement is flexible and convenient. To achieve a general purpose, the design law is called the universal replacement design rule. Because the engineering design takes the maximum load, the design rule is also called the maximum load design rule.
3、 实施法则  3. Implementation rules
实施法则采用一次分段实施法则。 实施法则是终极开发的关键。 地下空间资源开发 不像地面建筑， 可多次重复再开发， 而地下空间开发后难以变换， 只能一次开发， 所以， 框架结构竖向 （深度） ， 采用一次终极开发。 城市交通为山峰形， 中区交通量多， 周边 交通量少， 地下空间开发是以城市中区逐一分段向周边延伸， 不断的加长、 加密， 逐步 形成地高路网， 确保路与车二者供需平衡， 所以， 道路 （纵向） 从功能上， 需要分段终 极开发， 实施法则由一次终极开发和分段终极开发构成， 法则统称为一次、 分段终极实 施法则 （简称终极实施法则） 。 实施法则遵循规划法则的道与车供需动态平衡的原则。 The implementation rule uses a one-step implementation rule. The implementation rules are the key to ultimate development. The development of underground space resources is not like ground buildings. It can be re-developed many times. After the development of underground space, it is difficult to change. It can only be developed once. Therefore, the frame structure is vertical (depth) and adopts an ultimate development. The urban traffic is mountain-shaped, the traffic volume in the central area is large, and the surrounding traffic is small. The underground space development is extended to the periphery by the urban central area one by one, continuously lengthening and encrypting, gradually forming a high road network, ensuring roads and vehicles. Balance between supply and demand, so the road (longitudinal) functionally needs segmentation Extreme development, the implementation of the law consists of a final development and segmentation of the ultimate development, the law is collectively referred to as the one-time, the ultimate implementation of the law (referred to as the ultimate implementation of the law). The implementation law follows the principle of the law of planning and the dynamic balance of supply and demand of vehicles.
乙、 点块结构终极法  B, point block structure ultimate method
点块结构终极法用于点法地下空间资源开发， 即基坑开发， 其结构形式有二： 一是 圆形点块结构法 （圆形结构法） ； 二是非圆形点块组合法 （非圆形组合法） 。 一、 圆形 结构法： 圆形结构法由圆形连续墙和虚拟底板组成， 结构底板上面， 圆形连续墙为支护 结构， 结构底板下面， 圆形连续墙为抗隆结构， 前者承担土压力水平荷载， 后者承担土 体隆起荷载。 根据基坑深度连续墙可分为多次错位施工， 虚拟底板采用 τ形沉井、 旋喷 搅拌桩二种。 底板设计和敷设根据抗隆监测确定。 二、 非圆形结合法： 非圆形即方形、 矩形等。 组合法是由结构法与作岛法组成， 即中间采用作岛法， 周边釆用结构法， 所以， 其法称为组合法。 点块地下空间资源利用与线性地下空间资源利用不同， 其用途和模式 因工程而异。  The point block structure ultimate method is used for the development of point space underground space resources, that is, foundation pit development. There are two structural forms: one is the circular point block structure method (circular structure method); the other is the non-circular point block combination method. Circular combination method). 1. Circular structure method: The circular structure method consists of a circular continuous wall and a virtual floor. Above the structural floor, the circular continuous wall is the supporting structure. Below the structural floor, the circular continuous wall is an anti-long structure. The former bears the soil. Pressure horizontal load, the latter bears the soil uplift load. According to the depth of the foundation pit, the continuous wall can be divided into multiple misplaced constructions. The virtual bottom plate adopts two types: the τ-shaped sinking well and the rotary jet mixing pile. The design and laying of the floor is determined by the anti-peak monitoring. Second, the non-circular combination method: non-circular, that is, square, rectangular and so on. The combination method consists of a structural method and an island method, that is, the middle method is used as the island method, and the surrounding structure method is used. Therefore, the method is called a combination method. The utilization of point space underground space resources is different from the utilization of linear underground space resources, and its use and mode vary from project to project.
由于地下空间资源开发利用受地质特性、 基坑深度、 场地周边建筑和开发用途等诸 多因素制约， 资源开发对岩土理论、 自然放坡等非结构理论仍需应用， 不能弃之。 结构 终极法为地下空间资源开发利用的核心和主体， 属于基本理论和方法， 结束人类社会长 期以来， 对地下空间资源幵发利用处于被动、 无序、 低效以及凭 "经验" 、 施工不安全 的历史。  Since the development and utilization of underground space resources are restricted by many factors such as geological characteristics, depth of foundation pits, buildings around the site and development uses, resource development still needs to be applied to non-structural theories such as geotechnical theory and natural grading, and cannot be abandoned. The ultimate method of structure is the core and main body of the development and utilization of underground space resources. It belongs to the basic theory and method. Ending human society for a long time, the use of underground space resources is passive, disorderly, inefficient, and based on "experience" and unsafe construction. History.
现将其优越性阐述于此： 1、 资源开发节约土地资源， 开辟地下多元地产， 城市也更 环保； 2、 医治 "城市综合症" ， 实现和谐、 秩序、 畅通交通和城市集约； 3、 克服物流 顽症； 4、 消弭内涝灾害； 5、 对目前汽车换代所需的基础设施 （充电或加氢） 能提供最 佳场地； 6、 汽车地下化对全球汽车产业的发展不无裨益； 7、 地下空间资源以公共隧道 模式开发， 有利于市政设施增设、 换代、 维护， 避免城市污染； 8、 工程施工安全， 造价 便宜。  Now its advantages are described here: 1. Resource development saves land resources, opens up underground diversified real estate, and the city is more environmentally friendly; 2. Heals "urban syndrome" to achieve harmony, order, smooth traffic and urban intensive; 3. Overcome Logistics stubborn; 4, eliminating internal disasters; 5, providing the best site for the current infrastructure (charging or hydrogenation) required for car replacement; 6, car undergroundization is beneficial to the development of the global automotive industry; 7, underground The development of space resources in the public tunnel mode is conducive to the addition, replacement and maintenance of municipal facilities and avoiding urban pollution. 8. Construction safety and low cost.
