earth excavation
soil excavation
Examples
- Earth excavation by mud - pumping technique and construction supervision
土方开挖泵吸施工工艺及施工监控 - Tony shaimuli plastic manufacturing , and processing ; hardware , for electricity , chemicals , needles textiles , stationery video sales ; turkmen excavation
塑料浓色母粒制造、加工；五金、交电、化工、针纺织品、文具电玩的销售；土方开挖。 - The idea of deep excavations traditionally rather pay more attention to stress than to deformation . calculation often ignores deformation caused by excavation . the model of calculation such as the rule of ultimate balance and the rule of 1 / 2 supporting have defects in fact
传统的深基坑支护设计观念以强度控制为主，在采用的计算方法上忽视了土方开挖后对周边变形的影响，所采用诸如极限平衡法、二分之一分担法等在模型上存在很大的缺陷。 - Researching on the technology if reverse order is to study strains if pits , structural systems if basement , environmental surwey and underpinnings . on account of emphasizing developing methods if checking strength if pick - ets , modemizing machenes of excavation and studying methods of underpinning is put forward and is a way if controlling the quality of pickets in sites , which leads an active effect ; synthetic application if rankintheory , spatial and time effect theory to excavation tl aanalyze the state of soil force and strain is brought forward and the time effect should be considered in the zone of clay , the formation and development of soil plasticity are analyzed and the most dangerous zone to decide how to excavate and where to begin is found ; analyzing the cause of picket settlement during reverse order and the differential settlement and discussing hlw to solute it . duringh the temporary survey and the environmental warship , bringing rorward the theory of environmental vibration and analyzing the state of soil force and probability of losing stabilization of soil under the effect of environmental vibration ; analyzing the state offeree in underground concrete wall by the method of mathematics and pointing out the place of the maximum force and deformation . based on systematic illustrating the reverse order , problems about application and development of reverse order and suggestions also are expressed
鉴于国内外的研究把重点放在大力发展工程桩的实验室承载力监测方法与设备、如何使土方开挖机械现代化及对周围建筑的临测方法上，本文提出了现场利用声波层析成像技术监测钢砼桩内部质量的方法与程序，并得出了声波层析成像技术是砼桩的动态质量检测的有效手段，这对指导施有积极、现实意义；提出了综合运用朗肯土压力理论、基坑空间和时间效应影响理论来分析逆作法施工过程中基坑边坡土体应力及应变的变化情况，指出粘土地区也应考虑时间效应，并且进一步分析了基坑边坡土体的塑性区形成和发展，找出边坡最不利的区域，以确定地下室土体的挖掘的方式和顺序，指出凭主观臆断与经验来施工是不可取的；在分析、经较逆作法与大开挖顺作法的地下室结构体系受力情况及施工顺序的不同，提出了节点处理技术；分析了逆作法施工期间桩的沉降变化原因及由此而产生的差异，并探讨了解决的方法；本文还提出了环境振动对土体边坡稳定产生影响的观点，并分析了在环境振动影响下，土体的应力状态及土休失稳破坏概率，并且还运用弹性力学知识和数学分析的方法定量地分析了地下混凝土墙受力状态，指出了被监测墙体的最大应力、应变位置。 - Based on the result of calculation and monitoring , the relationship between the displacement of diaphragm wall and the depth and speed of digging is analyzed . and also the influence to surrounding building caused by digging and precipitation during construction are discussed in this paper . so it is pointed out that digging and pore stake are the key influence factors on the safety of the whole support system
根据计算和监测成果，分析了地连墙墙体位移和挖土深度、挖土速度的关系，探讨了基坑开挖和施工中的降水对周边建筑物沉降的影响，指出深基坑土方开挖和孔桩施工是影响整个围护体安全的关键。
