摘要

新加坡东北线大部分隧道施工采用土压平衡盾构施工。定居点总体上控制得很好;然而，偶尔会有超过设计估计的大沉降、天坑或地面损失。大多数较大的地表沉降、地陷和地面损失可能与使用的面压不足有关。还审查了其他记录的EPB盾上沉降的经验，并反复发现了偶尔但较大的沉降或天坑的相同模式。在审查的许多案件中，与这种和解有关的因素也很常见。

LOCAL SETTLEMENTS AND SINKHOLES DUE TO EPB TUNNELLING

Most of the tunnelling for the North East Line in Singapore was carried out using earth pressure balance (EPB) shields. Settlements were generally well controlled; however, there were occasional large settlements, exceeding the design estimates, sinkholes or losses of ground. Most of the larger surface settlements, sinkholes and losses of ground can be related to the use of insufficient face pressure. Other documented experience of settlements over EPB shields is also reviewed and the same pattern of occasional, but large, settlements or sinkholes is found repeatedly. The factors associated with such settlements are also common in many of the cases reviewed.

期刊介绍： The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
