摘要

由于缺少建筑材料

在陕北风沙区采用风积沙作为筑坝材料成为一种选择。但沙坝内修建泄洪洞等水工建筑物后

运行过程中存在沉降问题。根据已建工程

采用原型观测和数值模拟方法

分析深厚覆盖层上沙坝内修建泄洪洞的沉降规律。沙坝泄洪洞的沉降在施工过程中就已经发生

竣工期沉降值在坝轴线附近达到24.35cm;上游洞段接缝处出现了不均匀沉降

而且随荷载增加

不均匀沉降更加显著。蓄水到1064.00m时

实测和模拟计算得到的最大沉降值分别为16.00、22.80cm

相差6.80cm

在同一位置附近出现。

Abstract

Due to the lack of building materials

using aeolian sand as dam filling material is an option in the sandy Region of North Shannxi.However

when the spillway tunnel and other hydraulic structures are constructed in the sand dam

the settlement issues arise in the course of daily operation.According to the project that has been built

using methods of prototype observation and numerical simulation to analyze the settlement law of the spillway tunnel built in the sand dam on the deep overburden.The settlement of the spillway tunnel during construction has occurred

and the maximum settlement value is 24.35 cm in the vicinity of the dam axis.The seams of the upstream tunnel section generate uneven settlement

and the uneven settlement is more significant with increasing load.When the elevation of the water in the reservoir is1064.00 m

the maximum settlement value of the prototype observation and simulation are16.00 cm and 22.80 cm

respectively.The difference between the two methods is 6.80 cm

and both of them appear near the same position.
